Like it was stated here, they have all your history in the computer. I traveled years to Thailand, never had problem entering. I have now a retirement visa, and I live here here with my wife. We left a month to Europe, had thought about the re entry permit, and yet had interrogation at the airport for an hour. I heard they are checking everything and making hard time for some these days. They asked about my retirement-visa, said, I had to follow Thai laws and respect the king. I stayed cool, and smiling, and said to them, if something is wrong, they should inquire with Chonburi immigration, who gave me the visa. And that I follow all Thai laws, and cannot be hold responsible if Chonburi immigration, made a mistake. After 30 minutes, it was ok, for me, but not for my Philippine wife. New discussion. The head officer, kept moving my passport for and back, would not surprised, that he expected a few bills in it. This the last thing I would do! Finally, he let us go, but when we passed the boot, again one of the officiers inside, said to him, something is wrong. But then he gave some instructions and we were stamped. Do not know what they see in the computer, to have all this trouble! But when we went to get our luggage, the officer came after us, and asked, if we could buy him chocolates for his trouble. Now, this was in March. They had probably time on their hands.
