LAFAYETTE - A Louisiana lawmaker who sponsored legislation that has prevented some foreign-born U.S. citizens without birth certificates from obtaining marriage licenses says she will push for an amendment.

A federal lawsuit filed Tuesday claims a state marriage law that took effect in January is unconstitutional and discriminates against immigrants.

After the suit's filing, Republican state Rep. Valarie Hodges told The Associated Press that she never intended for the 2015 measure to prevent legal immigrants from getting a marriage license. She called it "basically a technical oversight." Hodges has said the intent of the law was to prevent marriage fraud.

Viet "Victor" Anh Vo is a U.S. citizen who was born in an Indonesian refugee camp. He claims in his lawsuit that court clerks in three Louisiana parishes denied his application for a marriage license because he couldn't produce a birth certificate.
