Frequently asked questions
What visa do foreigners need for Thailand?
It depends on purpose: short stays are covered by visa exemptions or tourist visas for most nationalities, while employment requires a Non-Immigrant B visa plus a work permit, and long stays have dedicated options such as retirement and Long-Term Resident visas.
Do I need a visa to enter Thailand at all?
Many nationalities enter visa-exempt for short stays, but the allowed length and conditions vary by nationality and change over time. Always check current rules before booking, and note that every foreign arrival must now also submit a Digital Arrival Card.
What is the Long-Term Resident (LTR) visa?
A 10-year visa for qualifying professionals, wealthy global citizens, retirees and remote workers, with fewer reporting requirements than standard extensions. Eligibility is criteria-based and worth checking if you plan a long stay.
Can I switch visa types inside Thailand?
Some changes are possible in-country and others require leaving to apply at a Thai embassy. Which route applies depends on your current visa and target category, so confirm before letting a visa run short.
