Entry requirements
Visiting Israel
If you intend to visit Israel, the West Bank or Gaza as part of a longer journey in the region, you need to bear in mind that it is the official policy of almost all Middle Eastern and North African countries (except, principally, Egypt, Jordan and Morocco) to refuse entry to people who have evidence of a visit to Israel in their passports. "Evidence" includes not only Israeli stamps, but also Jordanian entry or exit stamps from the border-posts at the Sheikh Hussein/Jordan River Bridge, the King Hussein/Allenby Bridge and the Wadi Araba/Yitzhak Rabin crossing (Aqaba– Eilat), as well as Egyptian stamps from the border-posts at Taba (near Eilat) and Rafah in northern Sinai. Visas issued in Israel for travel to any country and flight itineraries that specify Tel Aviv (or TLV) will also bar you, as will anything in Hebrew discovered in your belongings.
The best advice is to construct your itinerary so that you visit Israel last, after Syria and the rest. Alternatively, you can apply in your home country, well in advance, for a second passport: many countries issue these to people travelling around the Middle East as a matter of routine, but it's then up to you to ensure that your tally of entry and exit stamps in each passport adds up, and that you don't hand the wrong passport over to the wrong border official.
