Relations shy of marital relations do not alter VISA requirements. So, if you needed a VISA before getting an Israeli boyfriend, you still need one and if you never needed a VISA before, getting an Israeli boyfriend does not change that. Most Western countries do not have a VISA requirement to visit Israel as tourists, so it is relatively easy. However, check the Israeli foreign ministry website (in the Related Links below) to check if your country has a VISA requirement to go to Israel. Note: The citizens of some Muslim countries, because of their government's non-recognition of Israel, are unable to acquire a VISA to visit Israel at all.

The Airlines flew him to Russia but when he landed the government put him on the first flight to Frankfurt and deported him.
