What should I put as the purpose of travel and do I need a return flight date when using a non-immigrant O spouse visa to travel to Bangkok?

When traveling to Bangkok on a non-immigrant O spouse visa, you can indicate various purposes such as "visit family" or simply "holiday". It's generally advisable to leave the return flight date blank, especially if you're planning to stay long term. However, some travelers suggest that a return or onward ticket might be necessary to avoid issues during boarding. Ultimately, experiences vary, with some recent travelers mentioning they faced no questions regarding their travel details.
