Republican Sens. Thom Tillis of North Carolina and James Lankford of Oklahoma on Monday proposed legislation that would force illegal immigrants who are using the Deferred Action for Childhood Arrivals program to meet tougher requirements as a condition of staying in the United States, and would also crack down further on illegal immigration.

The Solution for Undocumented Children through Careers Employment Education and Defending our Nation Act, or the SUCCEED Act, is meant to be an alternative to the Dream Act, which other senators are pushing as a solution to allow immigrants who entered the U.S. illegally as children stay and work once DACA is rescinded in March.
