Thailand Notice

Currently, Thailand allows Americans to stay 30 days in country with a valid U.S. passport. All those wishing to stay beyond 30 days must apply for a tourist visa. OSSO cannot guarantee that a visa will be issued. Volunteers will be responsible for all costs of acquiring the visa and costs associated with a visa being denied such as airfare-change fees, government fees, etc.

If you plan to stay in Thailand for longer than 30 days, please visit this link.
