On April 30, the Department of Homeland Security announcement changing worksite immigration enforcement.
The new DHS guidelines focus on criminal prosecutions of employers who knowingly hire unauthorized workers. In 2008, large-scale raids resulted in more than 6,000 arrests, only 135 of whom were employers. In recent years DHS launched raids based on tips that an employer was hiring unauthorized workers rather than being the result of Immigration and Customs Enforcement (ICE) investigations of employers, making it difficult to secure adequate evidence to result in prosecution. The new guidelines emphasize investigating and criminally prosecuting abusive employers thus honing in on one of the root causes of undocumented immigration.
