Authorities say a man born in Kuwait has been convicted of marriage fraud in Nebraska.

A news release from the office of U.S. Attorney Deborah Gilg (gihlj) says 47-year-old Ibrahim Matari was sentenced to time served and was given 30 days to leave this country.

Prosecutors say Matari came to the United States in 2000 on a student visa and remained after it expired. He and his family lived in Oak Park, Ill.

Prosecutors say he obtained a marriage license with a U.S. citizen in Douglas County, Neb., in August 2009. They married and soon filed a petition to adjust Matari’s status.

Federal officers interviewed them and discovered the sham. The woman, Crystal Foster, has pleaded guilty to harboring an alien and is scheduled to be sentenced on June 7.
