Thai immigration uses short form numbers for its main paperwork: the TM.7 extends your stay, the TM.8 is a re-entry permit, the TM.30 notifies immigration of where you live, the TM.47 is the 90-day report, and the TDAC is the online arrival card that replaced the TM.6. This glossary explains what each one is, who needs it and when. It does not walk you through filling in the forms.

Thai immigration terms
| Term | Meaning |
|---|---|
| Visa validity | The window in which you can use the visa to enter Thailand. It is not the same as how long you can stay on each entry. |
| Stay permit (permission to stay) | How long you may remain in Thailand on a given entry. An extension of stay adds days to it. |
| Extension of stay | Extra days added to your current stay permit at a Thai immigration office, using the TM.7. It is not a new visa and does not change the visa you entered on. |
| Re-entry permit | A separate stamp that lets the holder of a single-entry visa leave Thailand and return on the same visa. Without one, a single-entry visa is cancelled when you leave. Multiple-entry visas such as the DTV, the Non-OA and the LTR do not need one. |
| Single-entry and multiple-entry | A single-entry visa covers one entry. A multiple-entry visa lets you leave and return as often as you like until it expires. |
| 90-day report | A legal requirement for foreigners staying long-term to confirm their address with immigration every 90 days, using the TM.47. Filing it does not extend your stay. |
| Border run (visa run) | Leaving Thailand and re-entering to start a new stay. Entry is always at the immigration officer's discretion, and repeated visa-exempt entries in a row can lead to questioning or refusal. It is not a long-term plan; a long-stay visa is. |
| Visa exemption | Entry without a visa for eligible passports, for a set number of days. One 30-day extension is possible. See Thailand's visa exemption rules. |
| DTV | Destination Thailand Visa: valid for 5 years, with stays of up to 180 days per entry, and evidence of financial assets of at least 500,000 THB [7]. |
| LTR | Long-Term Resident visa, run by the Board of Investment (BOI). The visa fee is 50,000 THB per person per 10 years [8], and holders report once a year instead of every 90 days [6]. |
| Non-OA | A long-stay retirement visa applied for at a Royal Thai embassy or consulate abroad, issued as a 1-year multiple-entry e-visa. |
| BOI | Board of Investment, the Thai government agency that runs the LTR programme [6]. |

Frequently asked questions
What is the difference between the TM.30 and the 90-day report?
The TM.30 tells immigration where a foreigner is staying, and it is filed by the landlord, host or hotel within 24 hours of arrival. The 90-day report (TM.47) is your own report confirming your address every 90 days of a long stay.
Is the TDAC the same as the TM.6?
The TDAC replaced the paper TM.6 arrival card from 1 May 2025. It is completed online, before you arrive, on tdac.immigration.go.th.
Do I have to pay for the TDAC?
No. The official TDAC portal says no fees are required. A site that charges you is a private service or not the official site.
How much is a Thai extension of stay?
The government fee for an extension of temporary stay (TM.7) is 1,900 THB. Short-stay entries such as visa exemption can usually be extended once, by 30 days.
Do I need a re-entry permit on a DTV?
No. The DTV is a multiple-entry visa, so you can leave and return without a re-entry permit. You need one only on a single-entry visa you want to keep.
How often must LTR holders report?
Once a year. The LTR replaces the 90-day report with a 1-year report and exempts holders from needing a re-entry permit.
