This is often a false choice in reality - many H1B recipients have lived here for decades or more, have kids at school who are American citizens and know nothing about where their parents even came from.

To go back deports their American children to a country where they may not even know the language, as one example.

I wouldn’t go as far as to call it slavery either of course, but it undoubtedly has a servitude element - the outcomes of the policy speak to that.
