USCIS updated its policy manual on April 7, 2020, to include additional information and eligibility requirements for Liberians and family applying for green cards under the Liberian Refugee Immigration Fairness Act (LRIF). The new policy guidance provides clarity on who qualifies for residency under the law and explains how USCIS interprets other provisions of this new law.
