A DN business visa approval letter is for business visits without a Vietnamese labour contract — meetings, negotiations, market surveys, installation or warranty work. The sponsoring Vietnamese company needs form NA2, its enterprise registration certificate and form NA16 on file; the traveller needs a passport valid six months. DN visas run up to 12 months (first-time sponsors often get three), service from 2,900,000 VND; DN does not allow employment or a residence card.
This page lists the conditions and documents for the DN category. The filing timeline is covered in the DN process guide; general approval letter steps are here.
Conditions
- The sponsor is a Vietnamese entity in lawful operation — enterprise, branch, representative office or project office.
- The visit is for business purposes without a Vietnamese labour contract: meetings, negotiation, market survey, project supervision, equipment installation or warranty work.
- The passport is valid at least six months beyond the intended entry.
- The company has form NA16 on file with the Immigration Department.
Documents from the sponsoring company
| Document | Notes |
|---|---|

| Form NA16 | First-time sponsors, or after a change of seal, legal representative or address |

Documents from the traveller
- Passport bio page scan — clear, all four corners visible
- Intended entry date and requested duration
- Entry gate or the embassy where the visa will be collected
Duration granted
DN visas run up to 12 months. Whether you receive 1, 3, 6 or 12 months depends on the justification in the file and the company profile; first-time sponsors are commonly granted three months, extended later with form NA5.
Where DN stops
DN does not permit employment and does not lead to a residence card. If the person will be employed, plan for a work permit and an LD visa from the start — converting later costs a second filing.
