those are some of the reason the regulation changed, and with the way things are now there are grounds to do something, before it was different, the burden was on a foreigner, so as u said whatever, foreigners don’t count for nationality issues.
But now technically is a national who has to give up his previous nationality, and that’s discrimination.
I do not need to care about other countries’ legislations on the matter, they are irrelevant for this matter. I care about how the current TW legislation is, not how it was and not worth to think about how it could be.
