Hello the community. I'm french nationality and plan to come in Thailand to claim a retirement extension to a non-immigrant O visa. I'm married with a thai spouse since 30 years. We live in Prachuap Khiri Khan. I'm actually in France and coming in Thailand next month. I need some explanation about the procedure to claim an extension retirement to non-immigrant visa O (not OA). I've seen your diagram explaining how to do but I need some more details. Coming in Thailand with a visa exemption 30 days, may I apply a non-immigrant visa leading to 1 year extension retirement at the immigration (Hua-Hin) ? I believe that it will be a non-immigrant O visa. Am I right ? I'm maybe confused with O (inside Thailand) and OA visa (out of Thailand). Thanks for all your advices.
