Claus Svensson You wrote in the original poster that you are in Hua Hin and want to get a ”Marriage Visa”. But you inform also later that you run into issues with the relevant embassy which I believe can be the Swedish seeing your name.
1. You apply for a Non-O Visa based on marriage from outside Thailand. When you passing through Immigration when entering Thailand the Visa is cancelled and you instead get a ”Stay Permit of 90-days” stamped into your passport.
2. You can then visit a local immigration office in Thailand when you have less than 30 or 45 days (not knowing about what the Hua Hin local requirements are?) remaining of the 90-days Permit to Stay. And thus get a ”1-Year Extension of Stay (of the Stay Permit)”
Note! That’s if all requirements are meet and there are quite a few such…Some call the 1-year extension of stay incorrectly for a marriage visa. Is not!
The Swedish Embassy in Bangkok did f.y.i. stop to issue certificates from 1 September 2025 for registering marriages to a Thai national when the marriage did take place in Sweden.
As can be seen there are quite a few steps to be done before to travel to Thailand for be able to register the marriage in Thailand. That the marriage is registered in Thailand is required as to get a 1-year extension of stay based on married with a Thai national. And as I remember if just been married it has to be gone more than 60 days before the marriage can be registered also in Thailand.
Many takes help by an agent for the steps in Thailand and to not having to go to Bangkok etc.
