Hi please what should do if my employer deducted...

If your inquiry is about the employer refusing to pay your salary due to visa fees, find the following information:
The worker can file a complaint against the employer if the employer refuses to pay his/her salary.
The worker also has the right to file a complaint at the Ministry of Human Resources and Emiratisation.
Also, it is the employer who is obligated to pay the worker’s visa fees

A fixed-term employment contract cannot be terminated without the written consent of the employer
