ETA-IL
If you have a passport that is not from Israel, you must fill out a form called ETA-IL, which permits you to enter Israel, and it is good for two years or until your passport expires. If you already have a valid ETA-IL from previous trips to Israel, and your passport did not expire in the interim, there is no need for a new one.
Student Visa
At passport control at the airport in Israel, you will receive a three-month tourist visa (that small blue slip of paper that lets you out into baggage claim) that you must keep with your passport. We will help you renew that visa at the Interior Ministry. You will then receive a student visa valid until the end of the school year.
