We visited Xinsheng in person and spoke with an administrator, sorry I don’t have her name, but she speaks decent English (probably why they referred us to her via phone). Anyway, she showed us a form (in Chinese), which we were told is available at all other Taipei schools as well just ask. I think someone posted a link to this in another thread here, search “Xinsheng”. You first must enroll your child at your local school, assigned to your apartment. Then, ask for this form and complete it to transfer your child to the 2-year “CSL” program at Xinsheng. Do this early, as they only allow I believe 20 CSL spots to foreigners. She said that 1-2nd grade is normally not full, but 3rd+ can fill up at times. I didn’t ask if an ARC is required before enrolling, or if foreigners can use the child’s passport. I’ve seen comments on both sides of this issue on the forum but forgot to ask her doh! Hope this helps.
