Drew Angerer/2017 Getty Images(CNN) - A gay married couple in Georgia sued the US State Department on Wednesday for refusing to recognize their daughter as a citizen.
When they applied for Simone's US citizenship, the US consulate in London rejected their application, the release said.
A State Department spokesperson declined to comment on the lawsuit, saying it does not comment on pending litigation.
The lawsuit says that, "Because she is the child of two men, the U.S. Department of State evaluated Simone's citizenship under the standards only applicable to children 'born out of wedlock' and refused to recognize Simone's U.S.
It accuses the State Department of violating the immigration act, saying it unconstitutionally disregards the "dignity and equality of the marriages of same-sex couples," and discriminates against their children.
