You were the one who changed subject to be about “switching jobs”, presumably because that issue has less to do why companies want to hire non-citizens in the US. Up until that point we were talking about employees advocating for rights at their current jobs, which is the main thing undocumented workers or people on work visas have to worry about. You were clearly trying to go for the “just change jobs if you don’t like your employer” thing, which is why you changed the subject (and then accused me of doing that, for some weird reason).
