just don’t be a typical loud American tourist. Very simple entry just read the signs . There are people there to point you in the right direction. You will be fingerprinted and your passport will be stamped. Just make sure you have your boarding pass with your passport. If you only take carry on then you are out in 5 minutes after your passport is stamped. Don’t need to take anything except a backpack. You can buy anything you need once you are there.
