Approved 90 day non-o visa but reentered Thailand early
I applied and was approved for the 90 day non-o retirement visa in Vietnam. I had an emergency and flew out of Vietnam and flew back into Thailand before the retirement visa was approved just a few days later. I went to our local thai immigration to see if I could get my passport stamped with the visa approval letter in hand but I was told I had to fly out of Thailand and fly back into Thailand to have my passport stamped with the retirement visa stamp. Is there an alternative way without using an agency? TIA
