A top immigration official said federal agencies are working on an agreement that could make it tougher for illegal immigrants to get jobs.
Jock Scharfen is acting director of U.S. Citizenship and Immigration Services.
On Tuesday he said in Lincoln that his agency is working with Immigration and Customs Enforcement to take advantage of a computer system used by employers to check the legal status of new hires.
Illegal immigrants are often able to trick the system by using false identification. But Scharfen said the system is close to being able to alert employers to possible identity fraud.
The two agencies are discussing which cases should be targeted for enforcement.
