In order to enter the UAE, your passport will need to be valid for at least 6 months beyond your date of entry. Visitors from certain countries (including the US, UK, Canada, Australia, New Zealand and Republic of Ireland) are able to obtain a free 30-day visitor visa upon arrival. If you're from one of the countries on the list, there’s no need to apply for a visa before you travel. You can see the full list of visas and countries here on the Emirates website.
