US Citizenship and Immigration Services (USCIS) has outlined the five categories of family members eligible for a Green Card, clarifying the family preference system for relatives of U.S. Citizens and permanent residents. The update provides guidance on how applicants can adjust their status if they are already in the United States. The categories include spouses, children, parents, and siblings, with specific rules for each. The information is intended to help applicants understand their eligibility and the process for applying. The USCIS emphasized the importance of accurate documentation to support each application. This clarification comes as part of ongoing efforts to streamline the immigration process and ensure compliance with U.S. Immigration laws.
