Thanks for your both answers, my plan was to apply in Laos for a visa based on marriage and then I would had one month to get the money on my Thai bank. As I won't be able to go to Laos I was wondering if the Thai immigration will give the possibility to do it in Thailand...
Hi, is Chiang Mai immigration usually gives 30 days if you ask an extension due to COVID-19? I'm french and I have the letter from my ambassy. I can also show my cancelled flight.
