I have a planned business trip to Israel in July, the company I work for does a lot of business in the Middle East and I have visited countries such as Dubai, Oman, Doha, Libya, Abu Dhabi, Bahrain..My concern is, will it be a problem visiting Israel with these country stamps in my passport and also will it be a problem if I visit these Middle Eastern countries again with an Israel stamp in my passport?
Note that there are many countries that won't allow Israeli passport holders in, but only Iran, Kuwait, Lebanon, Libya, Qatar, Saudi Arabia, Sudan, Syria, and Yemen will actively reject passports that have the Israeli stamp in.
The rule is not always applied, so there are reports of those entering with Israeli stamps, but this is the exception to the rule.
