US B1/B2 Visa Application Support for Applicants in Vietnam
Structured preparation for the DS-160, supporting documents, and interview stage of a US visitor visa application — for tourism, family visits, or short-term business.
B1, B2, and the combined B1/B2
B1 generally covers short-term business activity; B2 covers tourism, family visits, and medical treatment. Most applicants from Vietnam are issued a combined B1/B2 visa covering both, though your purpose for any specific trip is still assessed each time you enter the US.
Section 214(b) — the most common refusal ground
The most common reason a B1/B2 application is refused is Section 214(b) — the officer isn't satisfied you have sufficiently strong ties to Vietnam to overcome the legal presumption that every visitor visa applicant intends to immigrate. This isn't a judgment about your honesty; it's a specific, narrow legal test about the evidence in front of the officer at that moment, and it can be reassessed on a stronger application.
What the application actually involves
At a high level: completing the DS-160 form online, paying the visa fee, scheduling biometrics, and attending a short interview at a US consulate or embassy. We help you prepare accurate, consistent DS-160 answers — inconsistency between the DS-160, your supporting documents, and your interview answers is one of the most common, avoidable problems we see.
Evidence of ties to Vietnam
Depending on your circumstances, this can include employment records, business ownership, property, family responsibilities, or enrolled study — organized so they present a clear, coherent picture rather than a disconnected pile of documents. There's no single document that 'proves' you'll return; it's the overall picture that matters.
Interview preparation
The interview is typically brief. Officers are assessing whether your stated purpose and circumstances are consistent and credible in the moment — we prepare you to answer clearly and truthfully about your situation in Vietnam and your reason for travel, which is rehearsal for clarity, not a script.
If you've been refused before under 214(b)
A prior 214(b) refusal isn't a permanent bar — there's no waiting period, and you can reapply as soon as you're ready. What matters is whether your new application meaningfully addresses the ties or evidence gap that led to the earlier refusal, rather than repeating the same case with the same documents. You're required to disclose every prior refusal on the DS-160; concealing one is treated far more seriously than the original refusal itself.

Common questions
What is a 214(b) refusal, exactly?
It's a refusal under section 214(b) of the Immigration and Nationality Act, where the officer wasn't satisfied that your ties to Vietnam were strong enough to overcome the legal presumption of immigrant intent. It's the most common reason B1/B2 applications are refused worldwide, not specific to any one applicant's honesty.
How long do I need to wait before reapplying after a 214(b) refusal?
There's no mandatory waiting period. What matters is whether you can present meaningfully stronger evidence than before — reapplying immediately with an unchanged case rarely produces a different result.
Do I have to disclose a previous refusal on the DS-160?
Yes, every prior visa refusal must be disclosed. Concealing one is treated as a serious misrepresentation issue, well beyond the consequence of the original refusal.
Can Covalyn get me a faster interview appointment?
No. Interview appointment availability is set and managed entirely by the US Department of State and the relevant consulate — we don't schedule, influence, or expedite appointments.
Does Covalyn guarantee my visa will be approved?
No. Every US visa application is decided independently by a consular officer. We help you prepare a clear, well-organized, consistent application — we cannot and do not guarantee the outcome.
