It's obvious to me that the problem with H-1B visas is the same as that of undocumented workers, in that we've created a second class of people who are trapped in a system seemingly created specifically to exploit them, while simultaneously making things worse for the rest of us.
It's my opinion that anyone already here should have a path towards citizenship, or legal permanent residence. The exploitation of people needs to end, and the dignity of everyone in this country should be respected.
Of course we need to have rules, and borders that are secure. It's unreasonable to want to abolish them or close them completely.
