It's hit or miss. A lot of the bad managers (and the world's full of 'em) just make sure most of their employees are on H1 visas so they can't plausibly quit.

It's hit or miss. A lot of the bad managers (and the world's full of 'em) just make sure most of their employees are on H1 visas so they can't plausibly quit. That way they don't have to do anything for the employees, and they don't have to worry about attrition. Not coincidentally, when things aren't as silly-boomy as they are now, being a citizen looks a lot more like being on an H1, and manager behavior often adjusts to match. Fair warning.
