A foreign investor residing in Vietnam on a DT card differs fundamentally from the labor category: their card stands on the project’s dossier, not on a labor contract. When the project changes its schedule or operating term, the residence dossier must be updated accordingly — in one irreversible order.
The mandatory order: investment first, residence second
- Adjust the project at the investment registration authority: the investor/project company carries out the investment registration certificate adjustment (extending the project implementation schedule, adjusting the operating term) under the Investment Law — the step that creates the new legal basis for residence;
- Update enterprise registration/charter if the schedule adjustment comes with enterprise information changes;
- Issue a new DT card at the immigration authority: on the adjusted investment dossier, through the project company’s sponsorship — processed in 5 working days under the residence card framework.
Reversing the order (applying for the card before the project is extended) bases the residence dossier on a project whose registered operating term is about to end — the usual result is a short card or a supplementation request pending the investment dossier’s completion.
Factors deciding the new card’s term
- The DT tier by capital: ceilings of 10/5/3 years for DT1/DT2/DT3 — a schedule extension does not change the tier; if capital simultaneously crosses a threshold, that is the upgrade story (see the DT3-to-DT2 article in this cluster);
- The project’s remaining operating term after extension: the card authority reconciles the card against the registered project lifespan;
- Passport validity: the card cannot exceed the passport expiry minus 30 days — investors with expiring passports should renew them before the new card cycle.
Starting time and attached documents
Good practice is to start the project adjustment at least 2–3 months before the current DT card expires (investment adjustment usually takes far longer than the residence procedure) and to file the new card as soon as the adjusted investment certificate is in hand. Do not forget the documents “riding” on the card cycle: the TT family cards of the investor’s spouse and children follow the main card, and — if the investor simultaneously holds an executive position in the labor category — their own work permit/confirmation is a separate dossier chain that must not be dropped.
Frequently Asked Questions
When the project extends its schedule, how is the investor’s DT residence card handled?
Following the investment → residence dependency chain: the investor completes the project adjustment (extending the implementation schedule or the operating term) at the investment registration authority to obtain an adjusted investment registration certificate; then uses the adjusted investment dossier as the document proving the card category and files for a new DT residence card at the immigration authority. A card still in validity keeps working normally during the adjustment — extending the project schedule does not void the current card; it is only the condition for issuing the next cycle’s card.
What documents prove the project has been extended?
The central document is the adjusted investment registration certificate (the latest version recording the extended schedule/operating term) — plus, as the receiving authority requires: the updated enterprise registration certificate, the company charter, documents on the investor’s capital contribution status (to determine the correct DT tier), and the sponsoring organization’s card request (the project company) on Form NA6 with Form NA8 and the investor’s passport.
Where is the new DT card filed and how long is it valid?
At the immigration authority (the Immigration Department or the Immigration Division of the provincial/municipal police) where the project company is based — through the sponsoring organization, the Vietnamese enterprise; processing follows the card framework of 5 working days. The new card’s term follows the ceiling of the DT tier matching the investor’s capital (DT1 up to 10 years; DT2 up to 5 years; DT3 up to 3 years), not beyond the passport expiry minus 30 days, and in practice aligned with the project’s remaining operating term after extension.
