In a July 1, 2009 news release, U.S. Immigration and Customs Enforcement (ICE) announced that it has stepped up its enforcement of I-9 rules, and has recently sent Notices of Inspection (NOI) to 652 businesses nationwide.

ICE stated that, "The notices alert business owners that ICE will be inspecting their hiring records to determine whether or not they are complying with employment eligibility verification laws and regulations... The 652 businesses being presented with a NOI today for a Form I-9 audit have been selected for inspection as a result of leads and information obtained through other investigative means."
