Absolute Border Control

This is what Newt Gingrich is calling for and I agree:

Former U.S. House Speaker Newt Gingrich says the United States needs absolute border control and to ensure new immigrants learn to be American.
Speaking in Oklahoma City on a book promotion trip, Gingrich said a guest worker program needs to ensure immigrants pay taxes, get driver's licenses, buy auto insurance and abide by the law, reports The Oklahoman.
"We have to have absolute control of the border because you have national security reasons," Gingrich said as he signed copies of his book, "Winning the Future."
"You want legal temporary workers who have background checks and sign a contract that they will obey the law, pay taxes and who can be removed from the U.S. in 48 hours if they break the contract," he said.

But what we do within our borders won't matter if the borders themselves aren't secured first.
