For example:

• something happens around Taiwan

• US announces new options for Taiwanese citizens in the US to extend their stay

or similar. The idea is that the US will take a pro-Taiwanese national stance re: immigration/legality/visa status of those people's presence in the US.

It doesn't have to be a specific policy, but has to be overall beneficial and help them avoid breaking laws, or avoid having to return to a country which is at war or occupied.

This includes changes due to military issues around Taiwan, but also to earthquakes, volcanos, etc. Since it's hard to distinguish. But, in any case, it must be a big change, applying to nearly all Taiwanese nationals in the US, not a small adjustment which is made for general purposes, but rather an action or change taken in response to real-world changes taking place in or near Taiwan.
