There is a visa requirement for Egypt and Discover Corps will handle these arrangements. You will receive the visa by hand upon arrival to Cairo.
Any international travel requires the use of a passport. If you do not have a passport it is important to apply for one as soon as possible. It often takes four to six weeks to process the paperwork for a passport (and even longer during the peak travel season of March to August).
For questions about obtaining or renewing your passport (American citizens), you can visit travel.state.gov.
Please verify that your passport is valid for up to 6 months after your scheduled departure date
It is also important that you have at least one completely blank page (with no stamps or visas) in your passport. This is a requirement for entry into many countries. If your passport is nearly full it might be a good idea to apply for additional pages.
Make several photocopies of your passport. Leave a copy at home with your family and carry a copy with you at all times when you are overseas for identification purposes, money changing, etc. If you should lose your passport, having a copy will speed up the process of replacing it.
