I am planning to stay in Thailand for about 6-7 months a year in the next two years and I have considered different visa alternatives. I understand that OA visa is multiple entry but it is not clear to me whether in each new entry (during the validity of visa) I will get one year permission to stay from the date of arrival or based on the last coverage day of the corresponding foreign insurance certificate.
Specifically, here is my preliminary plan:
1. I buy a foreign insurance from my home country (in EU) with the validity from Sep 1 2024 to August 31 2025.
2. I apply and obtain an OA visa valid from Sep 1 2024 to August 31 2025.
I have two questions:
a) If I arrive in Thailand in Sep 15 2024, do I get permission to stay until Sep 14 2025 (i.e. for one year from the date of arrival) or August 31 2025 (according to the expiry date of my foreign insurance)?
b) If I leave Thailand in April 2025 and return in August 1, 2025 with a new *foreign* insurance policy for the period August 1, 2025 to July 31 2026, is my permission to stay going to be until July 31 2026?
Please note that I am not planing to extend my OA visa in the immigration in Thailand and I will have a new one-year foreign insurance (not TGIA-associated insurance) in my return to Thailand in August 1 2025.
Cheers,
Jeff
