Hello sir

Although your query is not clear, here is the following information:
If two of your friends are facing problems due to illegal residence in the UAE, in that case they can search for work, and if they manage to obtain a work contract, a request can be submitted to amend the residence status with payment of all fines for violating the period of residence.
If they wish to leave the Emirates, they can submit a request to the General Directorate of Residence to reduce the fine by fifty percent.
And if you mean that your friends have been scammed, they can file a complaint with the police station
against the person who defrauded them, with the submission of evidence proving the validity of the complaint.
