Visas and Immigration: Staying in Thailand Legally

For many foreigners, Thailand is not just a holiday destination but a place to live

long-term. Whether you’re retiring, married to a Thai spouse, or planning to work

here, having the right visa is essential. Staying legally avoids fines, deportation, and

future travel restrictions.

old.
