US nationals can obtain a free 30-day visa upon arrival, which can be extended up to 90 days for a fee of Dhs 500.

Health and Safety
The crime rate in the UAE is extremely low. However, tourists should always be careful when traveling around the large cities at night as muggings and theft is not uncommon. Use common sense after dark, stay in groups and always inform someone of your whereabouts.
The UAE is extremely strict when it comes to drugs. Travelers have been thrown in jail just for having narcotics in their system upon arrival in the UAE, even if the drug was ingested outside the country. This includes alcohol. Some drugs that are legal in western countries are illegal in the UAE, including medicines with codeine. Always carry your prescription with you.
Another important health and safety tip for the UAE relates to driving. Rules of the road are rarely enforced, meaning motorists will do almost anything to get where they need to go. This includes speeding and ignoring red lights. The accident rate in the country is high and the death toll is the third highest in the world. Pedestrians need to be vigilant when crossing the street.
No matter what time of the year you visit, staying hydrated is of major importance. The weather can be extremely hot, increasing the likelihood of heat exhaustion and heat stroke. Wear loose clothing, drink plenty of fluids and remain sun smart while exploring the outdoors.
