Passport

Israel requires foreign passports to be valid up to six months past the entrance date into Israel.
It is recommended to carry your passport on you at all times, if not a photocopy. Security guards, checkpoint guards, and police officers may ask to see your passport.

Travel Between Middle Eastern Countries

Some countries in the Middle East do not grant visas or entry if you have a stamp from Israel. If you ask in advance, Israel will usually agree to not stamp your passport. Some people carry two passports for travel between conflicting nations.

It is highly advised to check news and embassy reports on safety when crossing international borders in Israel. Conflicts can arise on certain holidays and sometimes unannounced, which can be dangerous for those around the borders.
