Washington (CNN)A married same-sex couple living in London is suing the State Department over the determination that only one of their two sons is recognized as a US citizen.
Same sex couple sues State Department over decision on son's citizenship
According to a complaint filed in US District Court, US citizen Allison Blixt and her Italian national spouse, Stefania Zaccari, have two sons -- one carried by Zaccari and the other by Blixt. The couple say both children were conceived and born during their marriage, and they are both legal parents to their two sons, who, they argue should be eligible for US citizenship as a result.
However, the couple alleges the State Department notified them that Lucas, biologically born to Zaccari, is not a US citizen and was born "out of wedlock." The younger child, Massi, biologically born to Blixt, is apparently eligible for US citizenship.
"Allison and Massi may reside in the U.S. permanently because they are U.S. citizens," lawyers for the couple write in the court filing. "Stefania may reside in the U.S. permanently by obtaining a family-based immigrant visa based on her marriage to Allison."
"The State Department's policy, however, renders Lucas the only member of his family without the freedom to live in the U.S. permanently," the filing continued. "The State Department's decision to withhold from Lucas the same rights granted to his brother means that he will experience the indignity and stigma of unequal treatment imposed and endorsed by the U.S. government."
A State Department official declined to comment on the specific case, citing its long-standing policy not to weigh in on pending litigation.
However, the State Department's website notes that children born abroad through the use of so-called "Assisted Reproductive Technology" can be granted citizenship at birth only if the child is "biologically related to a U.S. citizen parent" who meets certain legal guidelines under the Immigration and Nationality Act, such as a minimum period of residency in the United States.
Under that interpretation, the State Department asserts that it is limited in its ability to grant citizenship to children born to same-sex partners abroad, even when the couple is legally married.
