For employees whose visas are sponsored by their employer, the renewal process is usually initiated by the company. The employer submits an application to the Ministry of Labor and immigration authorities, providing the necessary documents, including updated contract information, proof of salary payment, and confirmation of the employee's health insurance. The employee, in turn, must be prepared to provide a copy of their passport and other necessary documents upon request. It is important to remember that the employer's refusal to extend the visa directly affects the employee's continued residence in the UAE.
