I am wondering how the government knows how long you have actually been in Panama when they do not issue an exit stamp? I only received an entry stamp of which you can barely read as the ink was running out and went back to the states after 9 days. I am going back to Panama in June and when going to immigration won't it look as though I've been there the whole time? I am confused. I would think they would issue an exit stamp so they know exactly when you leave? Please advise if anyone knows.
