Resident Visa holders are required to apply for the Alien Resident Certificate and Re-entry Permit at local service centers of the National Immigration Agency within 15 days starting from the next day of their arrival. They may stay in the ROC as long as the Alien Resident Certificate remains valid.
If foreign nationals who have entered the ROC with Visitor Visas are subsequently legally employed in the ROC, they may make the necessary change from their Visitor Visa into a Resident Visa in this country directly. The above regulations do not apply to blue collar workers or those who enter the ROC via the visa exemption program or landing visa.
