Jamal Uddin has been disqualified as a director for six years after employing two illegal workers at his restaurant, Weymouth Tandoori in Weymouth, Dorset.
Home Office Immigration Enforcement Officers discovered the workers on 27 January 2015 at the restaurant, where Uddin was the sole registered director.
The disqualification prevents Uddin from being involved in the "promotion, formation or management of a company" for the duration of the disqualification.
The company went into liquidation on 31 July 2015, owing £33,802 to creditors, including a £20,000 penalty imposed by the Home Office Immigration and Enforcement.
Sue MacLeod, chief investigator of insolvent investigations, Midlands & West at the Insolvency Service, said: "Illegal workers are not protected under employment law, and as well as cheating legitimate job seekers out of employment opportunities, these employers don't ensure the appropriate tax is paid, and as a result can undercut honest competitors.
"The Immigration, Asylum and Nationality Act 2006 makes employers responsible for preventing illegal workers in the UK. To comply with the law, a company must check and be able to prove documents have been checked prior to recruitment, showing that a person is entitled to work in the UK."
