The updated policy directly impacts US government employees and service members, many of whom are temporarily assigned to posts overseas for extended periods. The policy says children living abroad with a parent who is a US government employee or US service member will not be considered to be " 'residing in the United States' for purposes of acquiring citizenship" under a section of immigration law.
Previously, their children would be considered to be both living in and outside of the US for purposes of eventually gaining citizenship. By stripping the children of the former, the only way they can get citizenship is through a parent applying for them, whereas before it would've been automatic provided they meet certain requirements, said Cristobal Ramon, senior policy analyst at the Bipartisan Policy Center.
USCIS says the policy could affect children of lawful permanent residents who naturalized after a child's birth.
The agency cited conflicts with the definition of "residence" in immigration law, as well as conflicts with State Department guidance, as reason for the change, according to the guidance.
