Make sure you are familiar with the passport and visa requirements for all of the countries you will travel to during your trip. Be aware that most countries require that your passport have at least 6 months validity and 2-3 empty pages before you reach the end of your trip. Depending on your nationality, some visas can be obtained upon arrival. However, it is very important to double check this information as it may change without prior notice.

Bamba recommends making scanned copies of all your important travel documents (passport, visas, student cards, insurance cards) and saving them to your email... just in case.

Here are two websites where you can check information on travel visas:
