Thailand Guardian Visa

For accompanying family in Thailand, the key is the Non-Immigrant O Visa (Family/Dependent), for spouses, parents (over 50), or unmarried children (under 20) of workers/students, requiring proof of relationship and the main family member’s status, with an initial 90-day stay and yearly extensions at Immigration after arrival; parents accompanying children studying can also get a Guardian Visa (Non-O), needing school letters and financial proof.
