I assume Foxconn, etc., have a lot of Chinese and Taiwanese workers on site to help bootup the facilities. But Apple's Houston facility is a real place: https://www.google.com/maps/place/8702+Fairbanks+North+Houst...
Foxconn bought it last year: https://communityimpact.com/houston/cy-fair-jersey-village/d...
That's... amusing.
It's the same situation as the Hyundai battery plant in Georgia last year. The foreign experts come to the US to teach us modern manufacturing. It's more accurate to describe it as Foxconn outsourcing to the US (for tax reasons), not Apple bringing manufacturing back home.
