I don't think the House immigration bill officially exists yet, but it when it does, it might have "legalization" instead of a path-to-citizenship. I think of "amnesty" as either of the above, but others have different definitions.
Is Paulsen opposed to the senate bill? To Obama's Dream Act?
Opposed to the Senate Bill, I can’t answer your 2nd question. I’m not well-versed on the topic, I’d hope he is.
