To correct an error on your Form I-94 (Arrival/Departure Record) or green card (Form I-551), the process depends on whether the error was made by U.S. Customs and Border Protection, USCIS, or resulted from incorrect information you submitted. If the error was made by the government, you can usually request a correction at no cost. If the error was your own, you may need to file a new form and pay a fee.

Correcting errors quickly is important, as mistakes on your I-94 or green card can cause problems with future immigration benefits or applications. For I-94 errors, you may need to contact CBP Deferred Inspection sites or use the CBP online portal. For green card errors, submit Form I-90 with documentation.
