Exchange students should apply for Resident or Visitor Visa in their resident country with the Admission Leffer of CGU before entering Taiwan.
Place to submit the application: ROC Embassy or Mission in your residence country (http://www.roc-taiwan.org/portalOfDiplomaticMission_en.html)
For more visa information, please visit http://www.boca.gov.tw/ct.asp?xItem=6139&ctNode=778&mp=2.
Visitor Visa: for exchange students study for one semester (less than 6 months)
Note: please do not enter Taiwan with visa-exempt entry. It is valid for 30-90days visit and is not extendable.
Resident Visa: for exchange students study for two semesters (more than 6 months)
Note: from previous students’ experience, it is likely that some ROC embassies issue visitor visas to international students instead of resident visas.
In this case, you can enter Taiwan on a visitor visa first and then apply for resident visa after you complete the registration.
