WASHINGTON (AP) - More U.S. businesses are about to feel the sting of the Obama administration's immigration enforcement strategy.

Immigration and Customs Enforcement says it has sent notices of inspection to 1,000 employers in the U.S., warning that agents will be scrutinizing their hiring records to check for employees working illegally in the U.S.

The administration has been using the audit tactic since 2009 and audited such companies as Krispy Kreme and Abercrombie and Fitch. An immigration official has said such audits doubled in 2010 over 2008.

ICE says the latest inspections will include employers of all sizes and in every state and that no single industry is being targeted nor is any one industry immune.
