I slipped up last year with not having the 400k for 2 days in the 2 month seasoning period. After more than 20 years was told that I had to start the marriage visa all over again. Went to Poi Pet, unfortunately and had to stay overnight. The Cambodian side was ok but the reception on the Thai side was awful. Rude and arrogant. Got back to Nakhon Sawan and was given a 90 day extension in order for the seasoning to take place once more. Finally got the new visa last week. An unpleasant experience when you're almost 80 years old
