>>>SAUDI ARABIA
Islam dominates all aspects of life in Saudi Arabia government policy, cultural norms, and social behavior. Islam is the only official religion of the country, and public observance of any other religion is forbidden. The Saudi government considers it a sacred duty to safeguard two of the greatest shrines of Islam, the holy mosques located in the cities of Mecca and Medina. Travel to Mecca and Medina is forbidden to non-Muslims. Muslims throughout the world turn to Mecca five times a day for prayer. Restaurants, stores, and other public places close for approximately a half-hour upon hearing the call to prayer, and Muslims stop their activities to pray during that time. Government and business activities are noticeably curtailed during the month of Ramadan, during the celebrations at the end of Ramadan, and during the time of the annual pilgrimage to Mecca, the Hajj. Travel facilities into, out of, and within Saudi Arabia are crowded during these periods.
Although Westerners have some leeway in dress and social contacts within company residential compounds, both men and women should dress conservatively in public. Womens clothing should be loose fitting and concealing, with high necks, skirts worn well below the knee, and sleeves below the elbow. It is recommended that women not wear pants.
Females are prohibited from driving vehicles or riding bicycles on public roads, or in places where they might be observed. Males and females beyond childhood are not free to congregate together in most public places, and a man may be arrested for being seen with, walking with, traveling with, or driving a woman other than his wife or immediate relative. In Saudi Arabia, playing of music or dancing in public, mixed bathing, public showing of movies, and consumption of alcoholic beverages are forbidden.
Saudi religious police, known as mutawwa , have been empowered to enforce the conservative interpretation of Islamic codes of dress and behavior for women, and may rebuke or harass women who do not cover their heads or whose clothing is insufficiently concealing. In addition, in more conservative areas, there have been incidents of private Saudi citizens stoning, accosting, or pursuing foreigners, including U.S. citizens, for perceived dress code or other infractions. While most such incidents have resulted in little more than inconvenience or embarrassment for the individual targeted, there have been incidents where Westerners were physically harmed.
U.S. citizens in Saudi Arabia should be aware of Saudi social practices, and that any infractions may be dealt with aggressively. If you are accosted by Saudi authorities, cooperate fully in accordance with local customs and regulations. U.S. citizens who are harassed by private Saudi citizens or Saudi authorities should report the incidents immediately to the U.S. Embassy in Riyadh or the U.S. Consulate General either in Dhahran or in Jeddah.
