This bill modifies how the federal government determines whether foreign-born children qualify as "immediate relatives" of U.S. citizens for immigration purposes. Currently, a child's eligibility for immigration benefits is based on their age at the time their parent becomes a U.S. citizen, which can result in older children losing eligibility if they age out before their parent's naturalization is finalized. The legislation would change this rule so that a child's age is assessed based on when the immigration petition is first filed, rather than when the parent completes naturalization, allowing more children to maintain their immediate relative status. This affects families in the immigration process where parents are seeking citizenship and have children who may be approaching adulthood. The bill does not include specific funding provisions or timelines for implementation.
