All Israeli citizens need an Israeli passport to travel outside of Israel. You can have passports of other countries, but you must use your Israeli passport when entering and exiting Israel. Children and babies must also have their own Israeli passport.
As of June 2017, all new Israeli passports are biometric. For more informations see the chapter About biometric passports below.
The information provided here is in English, however, the application process and relevant forms are provided in Hebrew. If you don’t speak Hebrew seeking assistance from a Hebrew speaker is recommended.
