When you land, you will pass through customs and immigration. During this process, government officials of your host country verify you are allowed to enter the country and that you are not bringing any illegal items into the country. This is a serious, although often tedious process, and should be given the utmost respect.
Have passport, visa and/or acceptance paperwork, as well as housing address readily available.
Keep all medications and dietary supplements in their original containers and if possible, bring a copy of any prescriptions from your doctor.
Follow the instructions provided to you by your program and proceed to the meeting point – it may be the airport or it may be your housing.
Anytime you cross borders – and when you return to the U.S. – you will go through this process again. Always carry your passport and entry authorization (visa or study abroad acceptance letter) when you cross borders.
