Form I-485 2026 Update: A-Number Auto-Fill Field Has Moved in New Edition

USCIS has released a new edition of Form I-485 (dated 09/18/26) that introduces a notable change to how the Alien Registration Number (A-Number) auto-fill feature works. In previous editions of the form, entering an A-Number on Page 1 would automatically populate the A-Number field in the upper-right corner of all subsequent pages, making form completion more convenient. In the new 09/18/26 edition, this behavior has changed. The A-Number field that controls auto-population across the form is no longer on Page 1. It has been relocated to Page 2, Part 1, Question 4. To trigger the auto-fill, applicants must navigate to that question, select 'Yes,' and then enter their A-Number in the designated field. This is an important practical note for EB-3 applicants and others currently preparing an I-485 adjustment of status application. Failing to enter the A-Number in the new location may result in the number not being populated on other pages, which could cause processing delays or requests for additional information. Applicants are advised to ensure they are using the latest 09/18/26 edition of the form and to follow the updated field location carefully. Always download the most current version of USCIS forms directly from the official USCIS website before filing.
