I entered Taiwan on Nov 10th, 2009 (from Vancouver). My original plan was to stay for 2 weeks. I was not sure how long my actual stay is going to be, and therefore decided to use my ROC passport to avoid the 30 day limit. I'm turning 19 next March and is aware that I have to leave the country before Dec 31 to avoid conscription.
Now My concern is that, with the holiday season and the winter Olympics, I find it very difficult to book my return flight to Canada. I've been on the waiting list for a couple of days now and still no answer from my airline.
I was wondering if I can avoid conscription by leaving Taiwan with my Canadian passport if I happen to leave after Dec 31st.
