Five construction contractors are facing trial on charges alleging they allowed illegal immigrants to work on their job sites.
At a hearing Monday, U.S. District Judge David Bunning turned down a request to delay the proceedings, and said trial would begin Nov. 27.
Federal agents in May raided several Fischer Homes work sites and arrested nearly 100 people, most of them Mexican or Central American nationals.
Five Fischer Homes supervisors were charged with conspiring to harbor illegal immigrants.
Defense lawyers said there has been no determination whether their clients were responsible for hiring and firing workers. The five defendants each face a maximum of 10 years in prison if found guilty.
The company has said it has done nothing wrong.
Most of the foreign nationals pleaded guilty to misdemeanor charges of being in the United States illegally and were deported.
