The US says children born abroad using assisted reproductive technology can now qualify for citizenship, in a move seen as a win for same-sex couples. To be eligible before, babies born overseas needed to be genetically related to the American parent. The change follows lawsuits from couples whose children were born using surrogates and other methods. Experts estimate the new policy will affect hundreds of families living outside of the US. The US Citizenship and Immigration Services (USCIS) policy, announced Thursday, means children of married couples where at least one parent is an American and one is related to the child, are eligible for citizenship and family benefits. The agency’s director, Ur Jaddou, said this new interpretation of the law is meant to ensure “fair access and support for all families and their loved ones”.
