What Is a Vietnam Visa Approval Letter and How Many Types Are There?

This page explains what an approval letter is. For the full filing procedure see the step-by-step guide; to have us do it, see the service page.

A visa approval letter — công văn nhập cảnh in Vietnamese — is a document issued by the Vietnam Immigration Department confirming that a named foreigner has been cleared to enter the country. It is not the visa itself: the visa is stamped afterwards, either at a border gate or at a Vietnamese mission abroad.

Two types by where the visa is collected

Airport / border pick-up Embassy pick-up
Visa issued at International gate in Vietnam (Tan Son Nhat, Noi Bai, Da Nang, land gates) The Vietnamese embassy or consulate named in the letter
Stamping fee paid In cash on arrival At the mission, in local currency
Photos needed Two 4×6 photos on arrival As required by the mission
Best for Travellers already booked to fly in Nationalities that must obtain the visa before boarding

Types by entry and duration

  • Single entry — one entry only; a second trip needs a new document.
  • Multiple entry — unlimited entries within the validity, better for regional managers commuting in and out.
  • Validity follows the visa symbol: 1–3 months for DL, up to 12 months for DN and TT, up to 2 years for LD, up to 5 years for DT1 and DT2.

Who can sponsor the letter

A Vietnamese company registered with the Immigration Department (form NA16 on file), or an individual sponsoring a relative. The sponsor signs form NA2 or NA3 and is responsible for the person invited.

Approval letter or e-visa?

An e-visa needs no sponsor but caps at 90 days and never allows work. An approval letter needs a sponsor but supports every symbol, longer stays and the route to a residence card.

Important: you cannot enter Vietnam before the date stated in the letter. If plans change, a new letter is required.
