When visiting Dubai, it’s important to follow local customs and laws. Do dress modestly, especially in public places, and respect local traditions. Use polite language, greet with \"As-salamu alaykum,\" and avoid public displays of affection. Respect prayer times and follow the legal drinking age (21). Don’t engage in offensive language, gestures, or behavior. Avoid drinking alcohol outside licensed venues or public spaces, and never use drugs as penalties are severe.
