UAE Authority has announced new travel rule
As per instructions from the UAE Authorities, passengers with a single name on their passports travelling on tourist, visit or any other type of visa shall not be allowed to travel to/from UAE.

“However, passengers with a single name on passports and in possession of a residence permit or employment visa shall be allowed to travel provided the same name is updated in the “First Name” and “Surname” columns.”
It means that people travelling on residence or employment visas will be exempt from the rule change.
Any passport holder attempting to enter the country with either just a primary or secondary name will be classified as inadmissible. The rules are effective immediately.
