The following information was provided by the U.S. State Department, as of June 25, 2015: For non-dual nationals, an onward or return ticket and proof of sufficient funds are required for entry. Although the Israeli government does not require that a passport be valid for six months from the date of entry, airlines routinely do so and may decline boarding if a traveler has less than six months validity on his or her passport. Travelers normally receive a free, three-month tourist visa upon arrival in Israel, which may be extended. Israel no longer stamps passports with an entry stamp, but instead provides all travelers with an entry card, although they reserve the right to stamp the passport. All travelers should retain this entry card throughout the duration of their stay in Israel as it is their proof of lawful entry. Although not required for exit, travelers are advised to have their entry card to avoid delays when departing Israel. Travelers carrying official or diplomatic U.S. passports must obtain visas from an Israeli embassy or consulate prior to arrival. Anyone who has previously been refused entry, has experienced difficulties with his/her status during a previous visit, has overstayed the authorized duration of a previous visit, or otherwise has violated the terms of a previous admission to Israel should consult the nearest Israeli embassy or consulate before attempting to return. Such immigration violations may incur a 10 year bar to re-entry into Israel. Click here for more details from the U.S. State Department. Click here for Israel's visa requirements by nation.
