Hi Tando,
First, thanks for so many helpful posts.
Second, I wanted to get your opinion on the 1-year grace period part, because I think it could help other people.
I read this law in Chinese: 歸化我國國籍者及歸國僑民服役辦法-全國法規資料庫
In 第三條二項, it uses the term 僑民. My assumption is that this refers to people that register as Overseas Chinese with the special passport marking. Since not every NWOHR may be eligible to apply for this for various reasons (i.e. maybe already lived in Taiwan for a year or two), does that mean that not quite every NWOHR can assume they can use this grace period, and those who want to use it must first make sure they apply for this 僑民 status?
If it helps, it looks like I posted this before and forgot:
