According to Taiwan Law, should the employer wish to hire foreign employee, the employer is required to apply to the Council of Labor Affairs and obtain the work permit first for the employee. This application takes approximately 2 weeks, and once the application is approved, a formal government letter will be forwarded to the employer, which serves as proof of permission for the employee to undertake employment in Taiwan.

 

Once the permit has been received, one can proceed to apply for resident visa. If the employee has arrived in Taiwan with a Visitor’s Visa, it might be changed without departing by making application to the Bureau of Consular Affairs at the Ministry of Foreign Affairs.
