Can I do this on my own without using your service?
Yes, but the steps are: (1) Register with Korlantas online, (2) Wait 2–3 weeks for International Permit to arrive in Taiwan, (3) Go to the DMV (監理所) in person on a weekday, (4) Fill out Mandarin forms, (5) If any document is missing, queue again. Many of our customers tried this themselves and contacted us after failing at step 3 or 4.
