TSMC looks to double down on U.S. chip factories as talks in Europe falter

I've been thinking about what would happen if there's an actual military crisis between China and Taiwan. I wonder if the United States would allow (and aid with) unlimited immigration from Taiwan for educated specialists, in an attempt to capture/retain as much skills and knowledge as possible.

In the event of a full-blown war the United States could just take possession and control of all foreign-owned fabs in the US.
