Can't answer for others, but I look at this law from the viewpoint of foreign workers, cause I am a foreigner worker. In Canada. Decided to absolutely never immigrate to the US due to the US blatant rise in xenophobia.
And the US has proven me correct over and over again in that assessment. Will watch with great pleasure the brain drain your country will face, and I honestly hope your economy will completely collapse.

The U.S. passed restrictive immigration laws in 1921. The foreign born population dropped to under 5% by 1970 (compared to 15% today). The decade on either side of that was a golden age for Silicon Valley.
