“Saudi Arabia, which is governed by strict Islamic law, requires citizens of almost every country to obtain a visa. People who wish to enter the country must have a sponsor; women, who must be dressed according to Saudi standards of modesty, must be met at the Saudi airport by a man who will act as a chaperone.
Saudi Arabia bans anyone with an Israeli stamp in their passport from entering the country, even in transit. Many Jews believe the kingdom has also withheld visas from travelers with Jewish-sounding names.”
