Read again: work visas. They can work, live and pay taxes but won't be granted eventual citizenship. It would be perfect for majority of undocumented workers who only want to save up and go back. This way gov will be able to track who's here, which is vital for national security.
The bill can also
-end birthright citizenship
-limit family reunification
-put focus on skilled immigrants!
This bill will have greater chance of bipartisan support and win-win for all!
I know lots of people would be angry about limited legalization and reunification but you CAN'T have everything. If dream act passes that will be enough!
