Phoenix ? Frustrated by the influx of illegal immigrants, some states are trying to make the United States less inviting to those who sneak across the border. Other states are moving in the opposite direction, trying to offer illegal immigrants many of the privileges citizens enjoy.

Lawmakers in Arkansas, Colorado, North Carolina, New Mexico and Nebraska have considered allowing the children of illegal immigrants to pay in-state college tuition rates. Iowa lawmakers have looked at making it easier for illegal immigrants to get driver’s licenses.

On the other side of the debate, a new Utah law will replace licenses for illegal immigrants with driving-privilege cards that cannot be used to board airplanes or register to vote. A Virginia lawmaker wanted to bar illegal aliens from attending the state’s universities.

The most restrictive measures lately have come from Arizona, the busiest illegal entry point on the nation’s porous southern border.

“We may not be able to secure the borders as we would like,” said Republican state Rep. Russell Pearce. But “we don’t have to allow them to get free stuff.”

Arizona voters last year approved a law that denies some welfare benefits to illegal immigrants. Now Arizona lawmakers are trying to bar illegal immigrants from attending adult education classes, obtaining child-care assistance or receiving in-state status at public universities or state-subsidized college financial aid.

Last month, the Pew Hispanic Center, a private research group, reported there were an estimated 10.3 million illegal immigrants living in the United States last year, an increase of about 23 percent from in 2000.
