did a covid extension in February at Caengwatthana to meet 2-month seasoning of 400,000 baht for the yearly extension of my Non-O marriage visa. They didn't ask me for letter from embassy. Apparently they want it now😏
One more detail: Although the officer from the front office gave me a covid extension application, I did not fill it in because I had already prepared this one for family extension. When checking the documents, the immigration officer handed me a blank covid extension form and told me to fill it out. That's what I did.
I have all documents including Affirmation of Freedom to marry, Affidavit etc. thanks for the shared experience. We will look for info from other places as well
