Which case are you?
The foreigners law lists every visa symbol in one place, Article 8. The list opens with NG1.
NG1 - Cấp cho thành viên đoàn khách mời của Tổng Bí thư Ban Chấp hành Trung ương Đảng Cộng sản Việt Nam, Chủ tịch nước, Chủ tịch Quốc hội, Thủ tướng Chính phủ.
NG1 is issued to members of a delegation invited by the General Secretary of the Communist Party of Vietnam Central Committee, the State President, the National Assembly Chairman, or the Prime Minister.
Law 47/2014/QH13, Điều 8, as amended

- You arrive as a tourist → DL, valid up to 90 days. The e-visa, EV, is valid up to 90 days too. See the e-visa guide.
- You work for a company or organisation in Vietnam → LD2 if you are subject to the work-permit requirement, LD1 if you are confirmed as not subject to it. Both are valid up to 2 years.
- You invest in Vietnam → DT1 to DT4, set by contributed capital or, for DT1 and DT2, by a Government-designated sector. DT3 covers capital from 3 billion to under 50 billion VND and is valid up to 3 years.
- You are the parent, spouse or child of a Vietnamese citizen → TT, valid up to 1 year. TT is one of the symbols that lead to a temporary residence card.
- You entered on an e-visa and now work → the purpose can be converted with a work permit or a confirmation that you are not subject to one.
- You visit relatives or study → VR, valid up to 180 days. DH, for an internship or study, is valid up to 1 year.
The table groups the symbols by maximum validity.

A visa’s validity must also end at least 30 days before the passport expires.
Every symbol, group by group
In the law, the D in LD1, DT1 and UD1 is the Vietnamese D with a bar. This page writes it as a plain D.

The e-visa and the newest symbols

Which symbols lead to a temporary residence card
Article 36 of the law sets out the cases in which a temporary residence card is issued. As amended by Law 118/2025/QH15, they include a foreigner temporarily residing in Vietnam who is eligible for a visa with a listed symbol.
The listed symbols are LV1, LV2, LS, DT1, DT2, DT3, NN1, NN2, DH, PV1, LD1, LD2, TT, UD1 and UD2. DN1 and DN2 do not appear in that list.
Members of diplomatic missions, consular offices and UN or inter-governmental offices in Vietnam are also among the cases, with their spouse, children under 18 and domestic staff. Their card is marked NG3.
A card marked LD1, LD2 or PV1 is valid up to 2 years. A card marked DT1, UD1 or UD2 is valid up to 10 years. Any card must end at least 30 days before the passport expires.

For eligibility, fees and steps in Nha Trang, see the temporary residence card guide.
One visa, one purpose
A visa cannot have its purpose converted, except in the cases below:
- documents proving you are an investor, or a representative of a foreign organisation investing in Vietnam
- documents proving you are the parent, spouse or child of the person who invited or sponsored you
- an invitation or sponsorship by an agency or organisation to work, with a work permit or a confirmation that you are not subject to one
- an entry on an e-visa, with a work permit or a confirmation that you are not subject to one
When a purpose is converted, a new visa is issued with the symbol and validity that match the new purpose. None of these four cases leads to DN1 or DN2.
