It is important to have an I 485 Interview Documents Checklist to ensure that all necessary documents are prepared and organized before attending the USCIS permanent residence interview. Having a checklist helps applicants ensure they bring all of the required documents, such as proof of identity and relationship, financial records, and evidence of eligibility for a green card. Additionally, having a checklist allows applicants to go through each item on the list and make sure all of their information is accurate and up-to-date.
