What can someone who lost her passport do to go...

To replace a lost or stolen passport, and before making an appointment to apply in person at a passport agency or center or your embassy to replace your passport.
Firstly and based on the formal 'lost passport certificate' that you can get from the police station, a person can apply for a new passport at his embassy/consulate in the UAE

When your passport is issued, you have to go back to the GDRFA to stamp your residence visa. 

In the event that the intended question is otherwise, you can kindly ask us in detail and we will respond to it in the shortest time frame.
