Important notice

What this service is and is not.

NamVisa is a document preparation assistance service based in Vietnam. We do not issue visas, represent any embassy, or provide immigration legal advice. Our role is limited to helping you review, organise, and prepare your documents for submission. U.S. immigrant visa applicants should consult a licensed U.S. immigration attorney for legal advice regarding their case.

Form Review Assistance

We help you review your DS-260 (Immigrant Visa Application) and DS-261 (Choice of Address and Agent) forms for completeness, accuracy, and consistency with your supporting documents. Forms are completed by you through the CEAC portal; we provide a secondary review.

Document Checklist & Organisation

A customised document checklist based on your visa category — DV lottery, family petition, or employment-based. We help you gather, organise, and prepare civil documents, financial evidence, and supporting affidavits.

Submission Guidance

Step-by-step guidance on how to submit your documents through the National Visa Center (NVC) and U.S. Consulate General in Ho Chi Minh City. We clarify what goes where and when, so nothing is missed.

Whether you have won the Diversity Visa lottery, your family petition has been approved, or your employer has filed an I-140 on your behalf, the document preparation phase is the critical bridge between petition approval and your interview. We help you cross that bridge with confidence.

FAQ

Common questions about U.S. immigrant visa document preparation.

We provide document preparation support for Diversity Visa (DV) lottery winners, family-based petitions (IR/CR categories), and employment-based immigrant visa applicants (EB-1 through EB-5). This includes form review, document checklist organisation, and submission guidance.

No. NamVisa is a document preparation assistance service based in Vietnam. We do not provide legal advice, represent applicants before USCIS or the U.S. Department of State, or substitute for a licensed U.S. immigration attorney. Our role is limited to helping you organise, review, and prepare your documents.

We provide form review assistance for the DS-260. We can help you review your entries for completeness, accuracy, and consistency with your supporting documents. The form must be completed and submitted by you through the CEAC portal.

Typical documents include a valid passport (6+ months validity), DS-260 confirmation page, appointment letter, two passport-style photos, birth certificate, marriage certificate (if applicable), police certificates, medical examination results, and financial evidence including the Affidavit of Support (I-864).

Yes. We can provide guidance on applying for a Vietnamese police clearance certificate (Phiếu Lý Lịch Tư Pháp) and assist with the process through our police checks service, available nationwide.

A U.S. immigration lawyer provides legal advice, represents you before USCIS and consulates, and can argue your case in immigration court. NamVisa provides document preparation support only — we help you prepare the paperwork but cannot give legal advice or represent you. For complex cases or legal questions, we recommend consulting a licensed U.S. immigration attorney.

Our service is designed for applicants currently in Vietnam. If you are a Vietnamese national living abroad and filing from another country for consular processing in Vietnam, we may still be able to help with the Vietnam-specific document preparation aspects. Contact us to confirm.
