A Green Card Documents Checklist is an essential tool for those who are applying for a Permanent Resident Card, or “Green Card,” in the United States. This document outlines all of the documents, forms, and other materials necessary to complete a Green Card application. Having such a checklist helps applicants ensure that they have all the necessary items required by U.S. Citizenship and Immigration Services (USCIS) and can help to avoid delays or errors that could cause their application to be denied.
