With British passport, process might be slightly easier, and she could get a work permit to teach English and her independent ARC, if she has a degree.
Well in that case you can at least sponsor a dependent ARC. It is pretty straight forward. If you arrive visa free make sure you enter Taiwan together (to avoid visa runs)
If you don’t mind me asking, why are you choosing Taiwan over Thailand?
I didn’t know Shane had started up in Thailand again. I thought the big guy had got banned.
The lowest wage you can get depends on how many teaching hours are available. 1500 pounds would be around 60,000NTD which feels to me like an average level for a new teacher in Taiwan. It’s around what I started at IIRC, and that was also with Shane.
I was perhaps wrong about Vietnam in that the people I know working there are very experienced.
