A border run (การเดินทางออกนอกประเทศเพื่อต่อวีซ่า, also visa run, bounce or out-in) is a trip out of Thailand and straight back in, made to obtain a fresh permitted stay rather than to visit the neighbouring country. A visa run, strictly, is the longer version: leaving to collect a new visa at a Thai embassy abroad before returning. No section of the Immigration Act B.E. 2522 (1979) forbids either, but entry on return is at the officer’s discretion, and the exemption rules from 15 September 2026 make the pattern harder to sustain.

What the law allows and what the officer decides
Section 12 of the Immigration Act lists the grounds on which entry may be refused, among them a foreigner without adequate means of support (section 12(2)), one without the money the Minister requires (section 12(9)), and one who does not meet the conditions of the visa or exemption relied on (section 12(1)). A foreigner whose passport shows six exemptions in a row and no travel elsewhere is, on the face of it, living in Thailand, and the officer may refuse. The refusal is made in writing and recorded. Section 22 allows an appeal to the Minister, lodged with the officer within 48 hours, except where the ground is section 12(1) or 12(10); an exemption refused for not meeting its conditions therefore has no appeal.
The numerical rule sits in the exemption notification. For years the Bureau has admitted no more than two visa-exempt entries through land border checkpoints per calendar year, and the notification published in the Royal Gazette on 31 August 2026 writes that cap into the exemption from 15 September 2026, when the stay also drops from 60 to 30 days. Nationals of Malaysia, Singapore, Brunei and Indonesia are outside the cap. Air and sea entries have no number, only the discretion described above.
Doing a border run in practice
The land crossings used are Aranyaprathet to Poipet (Cambodia), Nong Khai to Vientiane and Mukdahan to Savannakhet (Laos), Mae Sai to Tachileik (Myanmar) and Sadao or Padang Besar to Malaysia. The traveller is stamped out and in the same day. On return the officer may ask for proof of funds (10,000 baht per person or 20,000 baht per family, cash preferred at land borders), an onward ticket out of Thailand within the permitted stay and accommodation bookings. A new TDAC is filed for each entry.
The common mistake is the third land entry in a calendar year: the crossing is refused and the traveller is stuck on the wrong side with a used exit stamp. Poipet reports the highest refusal rate, and officers who suspect a pattern may grant only a few days. A visa run to Vientiane, Savannakhet or Penang avoids these problems because the traveller returns on a visa, but embassies now take e-Visa applications in advance and refuse applicants with a long chain of stamps.
Border run compared with a lawful long stay
| Option | Stay per entry | Limit | Risk |
|---|---|---|---|
| Visa exemption border run | 30 days from 15 September 2026 | Two land entries a year, discretion by air | Refusal at the border |
| Tourist visa run | 60 days, extendable by 30 | Embassy discretion | Visa refusal abroad |
| DTV | 180 days, extendable once | Five-year validity | Low, if documents are genuine |
| Extension of stay in Thailand | One year | Renewable | None, if conditions are met |
A run gives 30 days plus one 30-day extension for 1,900 baht; the same traveller on a DTV gets 180 days per entry for five years with one 180-day extension, and a retiree or spouse gets a year at a time through an extension of stay without leaving. A refused entry on the record follows the passport to every later visa application.
Last reviewed: 28 September 2026. Sections 12 and 22 of the Immigration Act B.E. 2522 and clause 3 of the Interior Ministry announcement on the 30-day tourism exemption (Royal Gazette, 31 August 2026) were read in Thai. The funds figures and the crossing points are practice and were not re-checked.
Frequently asked questions
Are border runs illegal in Thailand?
No law forbids leaving and re-entering, and a single run is unremarkable. What the Immigration Act does allow is refusal of entry under Section 12 to a foreigner who appears to be living in Thailand on tourist exemptions rather than visiting, so the risk is not prosecution but being turned back at the border with the refusal stamped in the passport.
How many border runs can I do in Thailand?
Through land border checkpoints, two visa-exempt entries per calendar year, counted from 1 January, a cap that is written into the exemption notification in force from 15 September 2026. By air or sea there is no fixed number, but each arrival is judged on the passport history, and repeated exemptions with no other travel lead to questions, short stamps and eventually refusal.
What is the difference between a border run and a visa run?
A border run is a same-day exit and re-entry for a new visa-exempt stamp, usually at a land crossing. A visa run is a trip to a Thai embassy or consulate abroad, such as Vientiane, Savannakhet or Penang, to obtain a new visa before returning, which gives a longer and more defensible stay but depends on the embassy accepting the application.
