There was a lady from China I knew who was working in a company in Silicon Valley. She probably has a Green Card or Citizenship by now, but if I recall correctly she was on an H1 visa at the time. If she lost her job for any reason, she would have had to find another employer pronto or she would have had to leave the country. Her employer did not find it hard to ask her to work from 8am to midnight 7 days a week.
