Any type of legalization that allows them to bring their family members over is unacceptable. Even if they're only given green cards, they'll be able to bring parents and siblings over. Like someone else said on this thread, this is just an anchor baby strategy under a different name.
Legalizing any illegal aliens will make it harder, if not impossible, to remove their parents, aunts, uncles, cousins, etc.
They don’t have to bring anyone else over, they are already here.
