⚠️ Thailand Immigration & Regional Travel Advisory

Thailand–Cambodia Border Advisory (Updated January 2026)

As of January 2026, several governments continue to advise against travel to parts of the Thailand–Cambodia border region, typically covering a zone of up to approximately 50 kilometres from the border.

Following armed incidents between Thai and Cambodian forces in late 2025, land border crossings in affected areas remain closed to foreign travellers, and the security situation is still considered sensitive. While an immediate ceasefire was announced on 27 December 2025, and no major new incidents have been publicly reported since, official travel advisories for the border area remain in effect at the time of writing.

Travel advice varies by country and may change with little notice. Travellers should always consult their own government’s foreign affairs authority for the most up-to-date and location-specific guidance.

Safety Advice

• Avoid all non-essential travel to border districts until advisories are officially lifted.
• Follow instructions from Thai authorities at all times.
• Stay informed via official government channels, local news, or information provided by your accommodation.

Outside the affected border areas, daily life and tourism in Thailand continue as normal, including Bangkok, Chiang Mai, Phuket, and other major destinations.

Thailand Immigration Update (November 2025)

Thailand’s Immigration Bureau has introduced stricter screening for travellers who repeatedly use visa-exempt entry to remain in the country long-term. There is no officially defined limit on the number of visa-exempt entries, but immigration officers increasingly assess a traveller’s overall travel and stay pattern. Those who appear to be living in Thailand through consecutive visa-exempt entries or frequent border runs may face additional questioning, warnings, denied entry, or refusal of extensions, even if they technically meet all entry requirements.

These measures target long-term stayers using border runs, not normal tourists. Genuine visitors with a standard travel pattern and a confirmed onward or return flight are not expected to be affected.

Summary of Entry Options ✈️

⛨ Health Insurance for Long-Term Stays

If you plan to stay in Thailand for more than a short visit, it is helpful to have international health insurance. Long-stay visas such as retirement, marriage, business, digital nomad, and most non-immigrant visas often require or strongly recommend reliable medical coverage.
