The following is a short list of U.S. companies caught with illegal aliens in their employ:

-Dunkin Donuts...George Valvanis, 53, of New Hampshire knowingly hired illegal aliens at several Dunkin’ Donuts stores in and around Portland, Maine. He conducted the illegal practice between 2001 and 2009.

In December 2010, Valvanis pleaded guilty to one count of engaging in a pattern or practice of recruiting or hiring illegal aliens unauthorized to work in the United States, and to one count of using a false attestation immigration document.

Valvanis could face up to five and a half years in prison. He will be sentenced in April.

-Chipotle Mexican Grills...In December 2010, Chipotle fired about 50 workers from several locations in Minnesota, after Immigration and Customs Enforcement apparently began an investigation into the immigration status of the restaurant chain’s workforce.

In a press release, Chipotle said: “We are fully cooperating with Immigration and Customs Enforcement officials in Minnesota in connection with a document request they have made.â€
