Local Laws and Etiquette
• Islam is an important aspect of UAE daily life, even in westernized Dubai. Emiratis adhere to Islamic codes of conduct and follow the five pillars of Islam (i.e., declaring that there is no god but Allah, praying five times a day, donating to charity, fasting, and making a pilgrimage to Mecca at least once in a lifetime). .
• Dress modestly: women should wear skirts to the knee or longer, tops with sleeves and nothing too tight or revealing; Men should wear trousers/jeans and tops with sleeves.
• Same-sex marriages are not recognized in the UAE and homosexuality is illegal; The country is considered one of the least hospitable nations in the world for LGBT+ people.
• Heterosexual couples should not show affection other than holding hands in public, especially during Ramadan when it is forbidden (as is eating and drinking in public in daylight) and could land you in jail. In November 2020, it was announced that extramarital cohabitation would be legalized in the United Arab Emirates. Previously, the law did not allow unmarried (heterosexual) couples to share hotel rooms, although in practice poof was generally not required.
