I have to agree that the scrutiny of documents here has increased significantly - and I support the suggestions of the previous poster.

In January, I arrived in Thailand with a 60 day tourist visa - but the officer stamped me in for 90 days. Though it was their error - when I left 45 days later (so within the 60 days) - there was significant consternation at immigration with the passing about of my passport back and forth to several officers and even an officer from the back room came out to look at it and they all took a VERY close look at the stamp and even the rest of my passport. ALL this even though - I was leaving within the 60 days - and any error was theirs.

No real problem though - and they never asked me about it. I stamped out fine and went on my way to return a week later on a different visa (Non-Imm B) - no problem.
