Immigrating to the U.S. in 2025: Why Does America Remain the “Promised Land”?

According to statistics from the U.S. Census Bureau, in 2023, more than 44.9 million immigrants lived in the U.S., accounting for approximately 13.6% of the population. This shows that America remains one of the world’s top destinations for those looking to settle and build a future:

• World’s Leading Economy: The US boasts the largest economy in the world, with a 2023 GDP exceeding 27 trillion USD. This creates countless job opportunities across various sectors. According to the U.S. Bureau of Labor Statistics, the unemployment rate in January 2025 was only 3.7%.
• Diverse and Open Culture: America is a multicultural nation that attracts the best from around the globe. This creates a rich, open, and colorful living environment that helps immigrants easily integrate and find their communities. Major cities like New York, Los Angeles, and San Francisco exemplify this cultural diversity.
• Advanced Education System: The U.S. has one of the world’s top education systems and is home to renowned universities such as Harvard, Stanford, and MIT. The QS World University Rankings 2024 noted that five U.S. universities were among the global top 10.
• Expansive Career Opportunities: The US is a hub for multinational corporations and innovative startups. Its competitive and dynamic environment facilitates career growth and success. Economic centers such as Silicon Valley, New York City, and Boston offer many attractive job opportunities.
• Immigration Policies: The US consistently offers programs and visa categories for highly skilled workers, investors, international students, and family-sponsored immigrants. According to the annual report from the U.S. Department of Homeland Security, more than one million green cards were issued in 2023 under family-sponsored categories.

Key Changes in U.S. Immigration Policy for 2025 to Note

At the time of this article’s publication, there is no official information regarding any major changes in U.S. immigration policy for 2025. Therefore, you should regularly check the websites of the U.S. Citizenship and Immigration Services (USCIS), the U.S. Department of State, or immigration law websites like the American Immigration Lawyers Association (AILA) to stay updated on the latest developments.

The Most Popular U.S. Immigration Categories for 2025

Recent statistics indicate that the most popular U.S. immigration categories include:

• Family Sponsorship remains the largest category, allowing US citizens or permanent residents to sponsor their relatives (spouses, children, parents, siblings) for permanent residency. According to USCIS, about 67% of green cards in 2022 were issued under family-sponsored categories.
• Skilled Worker Category: The demand for highly skilled workers in the U.S. remains high, especially in technology, healthcare, and engineering. Programs such as EB-2, EB-3, and H-1B are popular for professionals with specialized expertise.
• Investment Category: The EB-5 program continues to attract foreign investors who wish to obtain US permanent residency by investing in job-creating projects. Although the number of EB-5 visas may be lower than that of the family and skilled worker categories, it remains a fast-track route to a green card for the entire family.
• Student Category: According to the Institute of International Education (IIE), over one million international students studied in the U.S. during the 2022-2023 academic year. After graduation, international students can seek opportunities to remain and work in the U.S. through programs such as OPT and STEM OPT.

U.S. Immigration Requirements and Conditions for 2025

To be eligible for U.S. immigration, foreign nationals must undergo a rigorous screening process and meet strict requirements set by the U.S. government. These requirements are designed to ensure that immigrants are law-abiding, do not negatively impact the community, and meet national security standards. In addition to the specific visa category requirements, all applicants must satisfy general conditions and pass background and medical checks.

Background Check Requirements

USCIS will conduct criminal and security background checks on all immigrant visa applicants. This process includes fingerprinting and a review of your name through the FBI. The purpose is to verify the applicant’s eligibility, ensure community safety and national security, and confirm a clean criminal record.

Biometric Fingerprinting

To initiate the background check, you must attend a biometric appointment at a USCIS Application Support Center (ASC) to have your fingerprints, photograph, and signature collected.

After the biometrics are taken, USCIS will forward your file to the FBI for a criminal record check. The FBI’s response will confirm one of the following:

• That you have no administrative or criminal history.
• That there is some administrative or criminal history (in which case USCIS will conduct further investigation).
• That your fingerprints could not be classified for a criminal background check (a rare case that may lead to application denial).

FBI Name Check

The FBI performs a “name check” using various databases related to criminals and persons of interest, including the FBI’s Universal Index (UNI) and other related records. The FBI’s feedback to USCIS will be one of the following:

• NR (No Record): No matching record was found.
• PR (Potential Record): There is a match with your name, prompting further investigation by USCIS.

Meeting the Medical Requirements

To satisfy the U.S. immigration medical condition, you must undergo a medical examination and receive the required vaccinations at a USCIS-designated medical facility. Results from non-designated facilities will not be accepted.

Pre-Immigration Medical Examination

The medical exam includes a review of your medical history, a chest X-ray, blood tests, and urine tests. The US Embassy or Consulate will evaluate your exam results based on U.S. immigration medical standards.

Certain medical conditions may render you ineligible for U.S. immigration, including:

• Serious infectious diseases: Such as tuberculosis, syphilis, and other conditions as specified by the U.S. Department of Health and Human Services (HHS).
• Physical or mental disorders: Especially if they are associated with harmful behavior or a likelihood of recurrence.
• Substance abuse or addiction.

Vaccination Requirements for U.S. Immigration

U.S. immigration law requires that applicants receive certain vaccinations. The list of mandatory vaccines includes those for Diphtheria, Measles, Polio, Tetanus, Pertussis, Hepatitis B, Hib (Haemophilus influenzae type B), and COVID-19.

Important Note: Both the medical examination and vaccination for U.S. immigration must be carried out at facilities designated by the U.S. Embassy. In Vietnam, there are two designated medical centers – one in Hanoi and one in Ho Chi Minh City. For up-to-date addresses, please click here.

Visa Category-Specific Requirements

Skilled Worker Category

• Educational Qualifications: A bachelor’s degree is typically required, though some professions may demand higher degrees such as a master’s or PhD.
• Work Experience: Relevant work experience in the applicant’s field, usually a minimum of two years, is necessary. More extensive and specialized experience can be a significant advantage.
• Certificates and Licenses: For certain professions (e.g., healthcare, engineering, education), you may need to possess specific professional certifications or licenses. For instance, foreign nurses must pass the NCLEX exam to practice in the U.S.

Investment Category

• Investment Capital: The minimum investment required under the EB-5 program is currently $800,000 for projects in Targeted Employment Areas (TEA) and $1,050,000 for projects outside TEAs. These amounts may change per USCIS regulations.
• Source of Funds: You must prove the legal origin of the investment capital. USCIS will rigorously scrutinize the source to ensure compliance with laws and anti-money laundering measures.
• Job Creation: Your investment project must create at least 10 full-time jobs for US workers within two years of receiving conditional permanent residency.

Family Sponsorship

• Family Relationship: You must have a legally recognized and verifiable family relationship with the sponsor, who is either a US citizen or permanent resident (e.g., spouse, children, parents, siblings). Legal documents such as birth certificates and marriage certificates are required.
• Sponsor’s Financial Capability: The sponsor must demonstrate sufficient financial means to support you while you reside in the U.S. The minimum income requirements depend on the number of family members being sponsored and USCIS regulations.

Student Category

• Letter of Admission: You must receive an acceptance letter from a US college or university that is accredited. The institution must be certified by the SEVP (Student and Exchange Visitor Program) to issue Form I-20 for international students.
• Financial Capability: You need to prove that you have sufficient funds to cover tuition and living expenses during your studies. Documentation such as bank statements or a financial support letter from a relative is required.
• English Proficiency: You must provide an English proficiency certificate (such as TOEFL or IELTS) that meets the school’s requirements. The score requirements may vary depending on the institution and program.

English Language and American Cultural Requirements

Even though not every visa category requires an English certificate, a strong command of the language is crucial for your integration and success in the U.S. English is the official language and is used in every aspect of life. Moreover, familiarizing yourself with American culture, customs, and lifestyle will help you adapt more quickly. You can learn about American culture through books, films, websites, or by enrolling in cultural courses.

5 Steps for Completing the U.S. Immigration Process in 2025

Immigrating to the U.S. can be a complex and lengthy process, but if you understand each step and prepare thoroughly, the journey toward your American dream will be much easier.

Step 1: Identify the Appropriate Immigration Category

This is the first and most critical step. You need to assess your profile, educational background, work experience, financial capability, and family relationships to determine the most suitable visa category. Choosing the correct visa category will save you time and effort and increase your chances of success.

• Self-Assessment: You can search for information on the USCIS or the U.S. Department of State websites to learn about different visa categories and compare them with your profile. USCIS offers a “Find My Visa Category” tool to help you determine the most appropriate option.
• Expert Immigration Consultation: If you feel uncertain or overwhelmed about which visa category suits you best, seek advice from reputable immigration professionals. Established immigration firms such as Fragomen, Berry Appleman & Leiden (BAL), Greenberg Traurig, Deloitte, or Ernst & Young (EY) have experienced lawyers and specialists who can assess your case and guide you in choosing the right path.

Step 2: Prepare Your Documents and Required Papers

Once you have identified your visa category, you must compile all the necessary documents. The checklist may be extensive and complex, so you should:

• Create a Detailed Checklist: Research the specific document requirements for your visa category on the USCIS website or through expert guidance. USCIS provides checklists for each visa type.
• Translation and Notarization: Any documents not in English must be translated and notarized by a reputable translation agency experienced in immigration document translation to ensure accuracy and quality.
• Organize Your Documents Carefully: Ensure that all documents are complete, accurate, truthful, and arranged in the required order. Incomplete or inaccurate documentation can lead to delays or even the rejection of your application. It is advisable to double-check your documents before submission and make copies for your records.

Step 3: Submit Your Application and Wait for Processing

The submission process and processing time will vary depending on the visa category and the USCIS processing center involved.

• Submission Methods: Some visa categories allow online submission through the USCIS system, while others require mailing your application to a USCIS or National Visa Center (NVC) processing center.
• Processing Time: The processing period can range from several months to several years, depending on the visa category and USCIS workload. For example, the EB-5 category may take longer due to the high volume of applications. You can monitor your case status online using the case number provided.

Step 4: Attend the Visa Interview

For most immigrant visa categories, you will be required to attend an interview at the U.S. Embassy or Consulate in Vietnam.

• Interview Preparation: Familiarize yourself with common interview questions and practice answering them confidently, truthfully, and concisely. You can watch sample interview videos on YouTube or attend consultation sessions organized by immigration firms. Dress professionally.
• Frequently Asked Interview Questions: Interview questions typically cover your personal information, the purpose of your immigration, your plans for living in the U.S., your financial capacity, and more. Interviewers might ask about family relationships, work experience, educational background, or investment plans (if applying for EB-5).
• Tips for a Successful Interview: Remain calm and confident, and answer truthfully while staying focused on the questions. Provide brief and clear answers, avoid unnecessary details, carry all original documents for verification, and arrive on time or a little early.

Step 5: Receive Your Visa and Prepare for Your Journey to the U.S.

If your interview is successful, you will be issued an immigrant visa.

• Entry Procedures at the U.S. Airport: Upon arrival in the U.S., you will go through customs and immigration (CBP – US Customs and Border Protection). Have your passport, visa, and all relevant documents ready. Answer the officer’s questions truthfully and clearly.
• Essential Documents to Carry: In addition to your passport and visa, it is advisable to carry copies of important documents such as your birth certificate, marriage certificate, educational diplomas, professional certificates, health records, and any letters of employment or acceptance (for students).
• Post-Arrival Procedures: After entry, you will need to complete additional steps such as applying for a green card (permanent residency), obtaining a Social Security Number (SSN), opening a bank account, and finding accommodation. It is important to research living arrangements and immigrant support services in advance.

Popular U.S. Immigrant Visa Categories for 2025

The United States offers a variety of immigrant visa categories tailored to different profiles and purposes. Here are some of the most common ones:

EB-5 Visa (Investment Immigrant Category)

• Requirements: Invest a minimum of $800,000 (in a TEA project) or $1,050,000 (in a non-TEA project) in a commercial venture in the U.S. and create at least 10 full-time jobs for US workers within two years after obtaining conditional green cards. The investment project must meet USCIS requirements regarding project type, investment area, job creation, etc.
• Advantages: The processing time may be faster compared to other visa categories, and the entire family (spouse and unmarried children under 21) can receive green cards. There is no requirement for educational qualifications, work experience, or language skills.
• Risks: It requires a significant investment, and the project might carry risks that do not guarantee success. Choosing a reputable and secure EB-5 project is crucial.
• Costs: In addition to the investment capital, you must also prepare for expenses related to application fees, immigration lawyer fees, project management fees, and document review fees. The total cost for an EB-5 application can amount to hundreds of thousands of US dollars.

EB-3 Visa (Skilled Worker Category)

• Requirements: Applicants must have the relevant qualifications and work experience for the position offered by a US employer, and the employer must demonstrate that no qualified US worker is available for the job before sponsoring a foreign worker under the EB-3 category.
• Preferred Occupations: Nurses, engineers, programmers, teachers, computer systems analysts, financial managers, etc. (depending on the current labor market needs and the U.S. Department of Labor’s priority occupation list). The list of priority occupations may change from year to year.
• Process: Typically involves several steps, including obtaining a Labor Certification from the U.S. Department of Labor (which may take several months to over a year), filing Form I-140 (Immigrant Petition for Alien Worker) with USCIS, and after approval, submitting the DS-260 (Online Immigrant Visa Application) and attending an interview at the U.S. Embassy/Consulate. Processing time for the EB-3 category can range from 2 to 5 years or more, depending on the applicant’s country of origin and case specifics.

EB-2 Visa (Advanced Professionals)

• Requirements: Similar to the EB-3 but for those with higher qualifications (usually a master’s degree, PhD, or exceptional professional experience). The EB-2 category is designed for individuals with advanced degrees or those who demonstrate exceptional ability in fields such as science, arts, or business.
• Special Considerations: In some cases, applicants may request a National Interest Waiver (NIW) to bypass the labor certification requirement by demonstrating that their immigration would benefit the national interest of the U.S.

Family Sponsorship Visas (CR-1, IR-1, F-Series)

• Requirements: You must have a bona fide family relationship with a US citizen or permanent resident (spouse, children, parents, or siblings). Family-sponsored visas are divided into Immediate Relative (IR) and Family Preference (F) categories. IR visas are for spouses, unmarried children under 21, and parents of US citizens. F visas cover other family relationships, such as married children of US citizens, siblings of US citizens, or the families of permanent residents.
• Sponsorship Process: The US-based relative (sponsor) must file Form I-130 (Petition for Alien Relative) with USCIS and demonstrate their financial ability to support you. After approval, the case is forwarded to the National Visa Center (NVC) for processing and scheduling an interview at the U.S. Embassy/Consulate. Processing times vary based on the relationship and category, ranging from several months to years.

Student Visa (F-1) and Post-Graduation Immigration Opportunities (OPT, STEM OPT)

• Pathway Through Study: The F-1 visa is for international students who wish to study at accredited US institutions, including universities, colleges, or English language programs approved by SEVP. To obtain an F-1 visa, you must have an acceptance letter from a SEVP-certified institution, prove financial capability to cover tuition and living expenses and demonstrate intent to return home upon completion of your studies.
• Immigration Opportunities After Study: After graduation, international students may apply for Optional Practical Training (OPT), which allows them to work in the U.S. for up to 12 months in a field related to their studies. Graduates in STEM (Science, Technology, Engineering, and Mathematics) fields may be eligible for an additional 24-month extension of OPT, making a total of 36 months. During OPT, if an employer is willing to sponsor and the applicant meets the eligibility criteria, students may transition to work-based immigrant visa categories such as H-1B or skilled worker visas (EB-2, EB-3) for long-term residency.

Immigration Costs for the U.S. in 2025

Immigrating to the U.S. is an expensive process, so budgeting and financial preparation are critical. Major costs include:

• Application and Visa Fees: Fees for filing forms with USCIS (e.g., I-140, I-485, I-130, etc.) and visa fees at the U.S. Embassy/Consulate (e.g., DS-260 fee). These fees can vary by visa category and are subject to change, so it is advisable to check the USCIS (https://www.uscis.gov/) and Embassy websites regularly. For example, the current fee for filing Form I-526 (for EB-5) is $3,675.
• Translation and Notarization Fees: Costs for translating and notarizing personal documents, diplomas, certificates, etc. These vary based on the number of documents and the service provider.
• Medical Examination and Vaccination Fees: Costs for a comprehensive medical exam and required vaccinations at designated medical facilities. These fees can range from a few million to tens of millions of Vietnamese Dong, depending on the facility and required tests.
• Travel Costs and Airfare: The price of airplane tickets from Vietnam to the U.S. and travel expenses for visa interviews. Airfare costs depend on the time of booking, the airline, and the class of service – booking early often secures better prices.
• Immigration Consultancy Fees (if applicable): Fees for hiring an immigration lawyer or consultancy service to assist with your application. These fees can range from a few thousand to several tens of thousands of US dollars, depending on the level of service and the reputation of the firm.
• Initial Living Expenses in the U.S.: These costs are related to renting a home (deposits and the first month’s rent), purchasing household items, and living expenses (food, transportation, utilities, internet, phone, etc.) upon arrival. According to Numbeo, the average monthly living cost for one person (excluding rent) is approximately $1,200 – $1,500, with higher expenses in major cities like New York or San Francisco.

Advice and Tips for Successful U.S. Immigration

To increase your chances of a successful U.S. immigration process, consider the following advice and tips:

• Stay Updated on the Latest Immigration Policies: U.S. immigration policies are subject to change frequently. Regularly check official sources such as USCIS and the U.S. Department of State, reputable immigration organizations, and legal bulletins for the most recent updates.
• Prepare Complete, Accurate, and Truthful Documentation: Your application is the key factor in your success. Take your time to compile a thorough, accurate, and truthful application with all the required documents. Providing false or incomplete information can result in delays or outright denial, affecting future visa applications.
• Seek Assistance from Reputable Immigration Experts: If you lack experience or feel overwhelmed by the complexity of the process, consult a trusted immigration lawyer or firm. Their expertise can help you choose the right visa category, prepare your documents correctly, and resolve any issues during the review process.
• Develop a Robust Financial Plan: U.S. immigration requires a significant financial investment. Plan your finances carefully, budget for all necessary expenses, and ensure you have a stable financial foundation to support your initial period in the U.S.
• Prepare for Cultural and Language Integration: Life in the U.S. can be quite different from Vietnam in terms of culture and customs. Improve your English skills, learn about American culture through books, films, and online resources, or take cultural orientation courses. Connecting with local Vietnamese communities can also ease your transition.
• Be Patient and Allow Yourself Time to Adapt: Cultural integration is a gradual process. Do not expect immediate adaptation – give yourself time to learn, adjust, and thrive in your new environment.

FAQs About U.S. Immigration

Can I apply for an immigrant visa on my own, or do I need an immigration lawyer?

You can certainly apply on your own if you are confident and willing to invest the time to research and understand the process. USCIS provides comprehensive information and guidelines on its website. However, hiring an immigration lawyer can be beneficial – especially for complex cases – as statistics show that applications prepared with legal assistance tend to have higher success rates. An immigration lawyer can:

• Assess your case and recommend the most suitable visa category.
• Guide you through the document preparation process to ensure everything complies with USCIS requirements.
• Represent you in communications with U.S. immigration authorities and help resolve any issues that arise.

How long does the U.S. immigration process typically take?

The processing time for U.S. immigration applications varies significantly depending on the visa category, the USCIS processing center (e.g., California Service Center, Texas Service Center, Nebraska Service Center, Vermont Service Center), and current processing conditions. Processing times can range from several months (for immediate relative categories) to several years (for categories such as EB-5 or skilled worker visas). You can track your application status online using the case number provided.

How do I prove my financial capability to qualify for U.S. immigration?

Financial proof requirements differ by visa category. Generally, you must demonstrate that you have sufficient funds to support yourself without relying on US public assistance. Common documents include:

• Bank statements and savings certificates.
• Recent bank account statements covering the last six months.
• Documents showing income from salary, business, rental, dividends, etc.
• Proof of ownership of valuable assets such as property, vehicles, stocks, or bonds.
• A financial support affidavit (if applicable) from a relative or friend in the U.S., along with evidence of their financial stability. Ensure that all financial documents are valid and, if necessary, translated and notarized.

Can I bring my family (spouse and children) with me when I immigrate?

Yes, most immigrant visa categories allow you to include your spouse and unmarried children under 21 as dependents in your application. Family sponsorship visas are designed to reunite families and allow US citizens or permanent residents to sponsor their relatives for permanent residency. Even categories like skilled workers, investors, or student visas typically allow accompanying dependents. You will need to provide legal documentation proving your family relationships (such as marriage and birth certificates).

What are the common mistakes when applying for a US immigrant visa, and how can I avoid them?

Common pitfalls include:

• Submitting incomplete or inaccurate documents – ensure you use a detailed checklist and review your application thoroughly before submission.
• Providing false or misleading information – always be honest and complete in your disclosures.
• Failing to demonstrate sufficient financial support – prepare all required financial documentation in advance.
• Poor performance during the visa interview – prepared by practicing answers to typical questions, dressing appropriately, and arriving on time.
• Choosing the wrong visa category – research all available options or consult an immigration expert to select the most appropriate one for your situation.

Can I bring my pet when immigrating to the U.S., and what is the procedure?

Yes, you can bring your pet (such as a dog or cat) when immigrating, but you must comply with strict quarantine, vaccination, and health regulations set by the U.S. Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture (USDA). The process can be complex and costly. The basic steps include:

• Ensure your pet receives the required vaccinations, including rabies, at least 30 days before your US entry.
• Obtain a health certificate from a licensed veterinarian.
• Securing an import permit from the USDA (if required by the state or type of pet).
• Arrange transportation with an airline that complies with animal travel regulations.
• Adhering to any quarantine requirements upon arrival, if applicable. For detailed guidelines, consult the U.S. Embassy/Consulate or the USDA website.

How do the U.S. education and healthcare systems compare to those in Vietnam?

The US education system is diverse and flexible, ranging from early childhood to higher education. American universities are renowned worldwide for their academic excellence and research facilities, though tuition fees – especially for international students – are significantly higher compared to those in Vietnam.

The US healthcare system is known for its advanced technology and high-quality medical services, but healthcare costs are among the highest in the world. Health insurance is essential to mitigate these expenses. While the quality of services may surpass that of Vietnam, the financial burden and the complexity of insurance plans are also considerably greater.

What cultural differences should I be aware of, and how can I adapt quickly to American life?

American culture differs from Vietnamese culture in several aspects, including its openness, direct communication, emphasis on individualism, and diversity. To adapt quickly, you should:

• Learn about American culture, history, customs, and core values such as individualism, equality, and freedom through books, films, and online resources.
• Improve your English proficiency and engage in regular communication with native speakers.
• Participate in community events, join clubs or organizations, attend cultural festivals, and volunteer to build relationships with Americans and other immigrants.
• Connect with the local Vietnamese community to ease your transition.
• Maintain an open, respectful attitude towards cultural differences and be eager to learn.
• Be patient with yourself – cultural integration takes time.
