Customs: Saudi Arabia forbids the importation, sale, or use of alcohol or illicit drugs. The government has and will continue to apply the death penalty to anyone convicted of possession of drugs with intent to distribute. In this conservative Muslim society, visitors must not import into Saudi Arabia any non-Muslim religious materials, pork products, or any material that may be construed as pornographic by Saudi censors. Cholera shots are required for entry for travelers arriving from areas where cholera is epidemic. All visa applicants must have a letter of invitation from an employer or Saudi sponsor.

Climate and clothing: Lightweight clothing is essential for the hot (38øC-54øC) climate. However, during the winter months in the interior regions (such as in Riyadh), the weather can be quite cool, so warmer clothing is recommended. Riyadh is dry, while Jeddah and Dhahran are humid most of the year. Western men and women should dress very conservatively. For women, skirts should be mid-calf length, sleeves elbow length, and necklines very modest; pants and pantsuits may attract unwanted attention.
