U.S. immigration officials put an unprecedented 1,000 businesses — including 42 in the Houston metro area — on notice Thursday that their paperwork would be inspected to make sure they don't employ illegal immigrants.
The announcement marks the largest round of immigration-related business audits ever, and the latest in an ongoing Department of Homeland Security campaign to create a “culture of compliance” with immigration law among employers, Immigration and Customs Enforcement Assistant Secretary John Morton said Thursday.
