> Can't people simply leave at will? Im actually not sure how this interacts with visas -- can visa employees freely leave without having to leave the country as well? It's anecdata, but when I interviewed with Amazon, not a single person born in the US interviewed me. (Which seems suspicious, that none of 7 people were from the US.) I've suspected that tech companies use visas to permit such toxic practices because foreign workers don't have the same negotiating position.
