This is helpful. I have had my ARC for up to 6 years now (through 3 different jobs) currently filling out the online app and will head over to MOFA later this afternoon to get this done. I believe this is what I need
Filled out application form
Valid ARC
Passport
Copy of passport
2 passport sized photos
Taiwan marriage certificate (English and Chinese)
Hard copy of Taiwanese spouses’s household registration
Spouses ID card
Hopefully no road blocks. I want to get this sorted with the chance that Taipei may end up closing up with the current worldwide situation.
