This document is your Travel Visa. BE SURE YOU KEEP THIS PIECE OF PAPER FOR YOUR DEPARTURE! You will be asked for it upon check-in for your return flight home. If you do not have this piece of paper, there will be a fine and the hassle of redoing all of this paperwork on the spot!Also during the flight you will be given a second document to fill out. This document is your Customs Declaration Form. You will need to present this to the customs official after collecting any checked luggage. Once you have presented your document, all of your carry on and checked luggage will be x-rayed. You will then be asked to press a button for a customs inspection. This is a random selection system.
