Vietnam visa extension for 3 months: Guide, Fees & Requirements 2026

A Vietnam visa extension for 3 months allows foreigners already in Vietnam to stay legally longer without leaving the country, provided they meet eligibility requirements. In most cases, applicants must have a valid passport, proper temporary residence registration, and a sponsor (company or family member, depending on visa type). The process involves submitting Form NA5, supporting documents, and paying the prescribed fee at the Immigration Department. Processing usually takes around 5–7 working days, depending on the case and workload at the time of submission.

Vietnam visa extension for 3 months: what it means in practice

A Vietnam visa extension for 3 months allows a foreigner who is already in Vietnam to stay legally longer (and in some cases keep the same entry conditions, such as single-entry vs. multiple-entry). In Vietnam, “extension” is often used in everyday conversations, but the outcome can vary by case:

Extend the stay (keeping the same visa type), or

Adjust/renew the visa validity (sometimes treated as a new visa issuance/adjustment), depending on your current status and the Immigration Department’s review.

That’s why the first thing we check at Tân Văn Lang is your current visa type, remaining validity, sponsor/guarantor status, and where you registered temporary residence.

What is a 3-month multiple-entry visa?

A 3-month multiple-entry Vietnam visa lets you enter Vietnam multiple times during the visa’s 3-month validity (each entry/stay conditions depend on the visa category and the granted stay period). This is commonly requested by foreigners who may travel in and out of Vietnam during the next 90 days.

Who can apply for a 3-month visa extension in Vietnam?

Not every visa can be extended the same way. In practice, extensions are typically considered for cases where you have a valid purpose and proper sponsor/guarantor documents.

Common visa categories that may be eligible include:

Family visit/dependent visas

Spouse/family-related stays (where a family member can sponsor)

Business/work-related visas where a company sponsors (e.g., business, work, investment-related purposes)

Basic eligibility checklist

To proceed with a 3-month Vietnam visa extension, you generally need to meet these conditions:

Passport validity: usually at least 3 months remaining (many cases prefer longer to reduce risk).

Clean immigration record: no active violations, no entry ban, and not under exit suspension.

Temporary residence registration: proof you have declared temporary residence in Vietnam (hotel/local police registration).

Sponsor/guarantor readiness:

For business/work/investment purposes: a Vietnam-based company acts as sponsor.

For family/dependent purposes: an eligible family sponsor and supporting relationship documents.

When visa run is used as a short-term workaround

Vietnam visa extension for 3 months

under your current conditions, some travelers consider a visa run (exit and re-enter with a new visa). This is not a “guaranteed fix,” and it depends on your nationality, current status, and entry rules at the time you apply.

If you’re close to expiry, we usually compare two options quickly:

Extension/adjustment in-country, vs.

Exit–re-entry with a new visa plan that matches your purpose.
