While I admire you detective work, to me the answers you have got are not definitive.
Especially in Taiwan, where the only black and white you can expect is possibly gray, or maybe yellow.
It reminds me of the traffic laws when I was studying for my drivers test for both a scooter and car.
There is a law stating you may not modify your scooter with all the neon flashing lights all over the place. The dude doing the riding test before me had a scooter that looked like it was straight outta area 51.
No problem.
The traffic cop did not seem to mind, and judging by the number or similar scooters I see, this seems to be commonly accepted.
Why should this case any different?
The point I have made on a few posts, is that what the law/regulations state is not relevant.
What is practiced in reality is.
Every buxiban owner, administrator etc, tells me you will not get an ARC to work legally teaching English, without the required passport.
I admit, I have spoken to only about 5 people personally, who have confirmed this, and Funkymonkey does too. None of these people have any reason to lie.
Shit, 99.9999% of the school owners would love an impoverished Eastern European, that they could pay NT $ 200 an hour to if they could. If they can,why don’t they?
The average parent would not know the difference between a Kiwi and a Khazakstani, even if it kicked them in the ass.
Pick a 100 buxibans to walk into, and you will not find a person legally working outside the 7 (obviously JFRV and APRC excluded).
