Make copies of everything you are taking with you. This includes your passport, visas, credit cards and any other identification you have. You can either take photos of it, scan it, or make traditional photocopies.  Either way, save a digital copy of each item in the cloud or email it to yourself, and also print at least two copies for easy access.

If your passport is lost or stolen, the US consulate or embassy is going to want to know your passport number, the issue date, and the expiration date. Other travel documents and credit card information should also be saved. (For credit cards, write down the international toll-free number of the card issuer too.)

Saving all this information about your essential documents in the cloud is excellent, but you may not always have wifi access. This is why two physical copies are a good idea. It offers you immediate access to everything you need.

Hide one set of your essential documents in your carry-on luggage and one other set in your checked luggage. That way you are covered even if your checked luggage isn’t available.
