YES! If you don’t already have a current U.S. passport, you may obtain one by picking up the forms at certain branches of the U.S. Post Office or go online to http://travel.state.gov/passport
Passports typically take six weeks to process.
Photocopy all important documents and keep them in a hidden place separate from the originals. Leave another copy at home with someone you can easily get in contact with while you are abroad.
