We would like to inform you that if you are asking about leaving the UAE and returning to it again with a valid residence permit, here is the following information:
The Federal Authority for Identity and Citizenship confirmed that there are no restrictions on the travel of residents of the Emirates abroad, and their return to the country. It also confirmed that there is no need to apply for a "return permit." However, it stipulated adherence to the announced health measures, including the application of a 14-day quarantine to those arriving after their arrival, even if the result of the COVID-19 examination was negative.
