If a foreigner who entered Taiwan with a resident visa needs to extend their residency in Taiwan, they should apply to the National Immigration Agency, bringing with them the relevant identity documents and other evidences （if the application is rejected, the application fee will not be refunded）. Persons falling into the following categories may not have their stay in Taiwan extended:

1. Persons who entered Taiwan through non-visa entry or with a landing visa.

2. Persons who have already exceeded their permitted stay in Taiwan.

3. Persons who have changed their visa category since entering Taiwan. A foreigner holding a 60-day visa that is not stamped "no extension permitted" may apply to the National Immigration Agency to have their visa extended, on presentation of the relevant documents.

When the individual goes to their Immigration service center to have their Alien Resident Certificate extended, the Immigration service center will issue them with an extension up to the date on which their passport will expire.

Once the individual's passport has been renewed or extended, they can apply to their Immigration service center for a further Alien Resident Certificate extension.
