1) Cut off the welfare freebees.
2) Heavy fines for all companies employing illegals.
3) Secure the border with the National Guard and a barrier (wall/fence).
4) Rescind the anchor baby laws.
And of course, to never reward their lawlessness with amensty.
I'd like to add one thing here... Employers who (knowingly) employ illegal aliens are contributing to identity theft. Those employers should also be required to pay all the expenses of anyone whos identity has been stolen, to recover their identity and credit. And they should be liable for all other costs as well.
