Securing the border solves part of the problem, but 40% of the illegals came here legally and overstayed their visas. We need more interior enforcement and a leveraging of state and local law enforcement with ICE to identify and deport the lawbreakers.
We also need to go after countries that refuse to take their nationals back. We have laws on the books that require us to stop issuing visas to nationals of countries that refuse to take their people back. We just don't enforce them.
“.....but 40% of the illegals came here legally and overstayed their visas.”
I think that the stat is that 40% of visa holders overstay their visas and are now here illegally.
Vastly more illegals just cross our southern border. Not just Mexicans, but people from all races and national origins.
