The principal applicants who have been approved by the immigration bill usually hold their original passports of their home countries and use them together with the US green card. This way, they can stay in the US indefinitely and enjoy the convenience of traveling back and forth to their home countries without the need to apply for any visa. For those who plan to apply for US citizenship and obtain a US passport in the future, there is usually no clear legal limit on the number of applications. However, if multiple applications are rejected due to ineligibility or failure to pass the exam, it may lead to stricter scrutiny by immigration officers. The key point is that you must meet all the legal requirements for naturalization each time you apply. And you must pay the corresponding application fee for each N-400 form you submit.

📅 Living requirements
- Continuous residence: A standard green card requires five years (three years for a spouse of a U.S. citizen), with a single departure usually not exceeding six months.
- Actual residence: The average green card holder needs to stay in the US for at least 30 months within 5 years (the citizen's spouse needs to stay in the US for at least 18 months within 3 years).

🆔 Age and identity

- Hold a valid permanent residence permit (green card).

📚 Language and civic knowledge

🔍 Moral trait

Yes, whether you are in Vietnam or other countries, you can directly apply for the U.S. EB-1A Outstanding Worker Immigrant Program. A key feature of EB-1A is that applicants can submit their application directly to the U.S. Citizenship and Immigration Services (USCIS), without needing a work invitation or sponsorship from a U.S. employer. However, applicants should note that their birthplace may affect processing delays. While green card applications for those born in Vietnam currently have no waiting period, the National Immigration Service (NIW) program does require waiting periods.

This guide outlines the timeline for each stage of the EB-1A Distinguished Individual immigrant program in the U.S., helping you stay on track: ① Submit application materials: 6-8 months; ② File I-140 form applications: 15 working days to 15 months; ③ Wait for NVC decision: approximately 1 month; ④ Receive interview and medical letter from U.S. Consulate General in Vietnam: 1-2 months; ⑤ Attend interview: 1 month; ⑥ Obtain entry visa: 7 days; ⑦ Departure to U.S.: 0-6 months.

The process typically involves an interview at the U.S. Consulate General in Ho Chi Minh City. Vietnamese applicants who have lived in the United States for an extended period—such as those holding valid long-term visas (F1, O1, L1) or individuals who have met the 90-day stay requirement after entering the U.S.—can complete their U.S. residency status conversion through Form I-485 without returning home. Additionally, some may be fortunate enough to receive an interview-exempt opportunity.
