We would like to inform you that in regard to visitor and tourism visas, the UAE government issued a decision for those whose visas have expired starting from March 1, 2020, a one-month deadline for departure from July 11, 2020 to August 11, 2020 without imposing any fines on you, noting that this period is renewable for one time for a month and you must leave even if your status has not been modified, and then if the violation is committed, a fine will be imposed on you for each day of delay in the country. 

In all cases you must review the General Administration of Residency for details.
