The U.S. Customs and Border Protection (CBP) will review and issue the necessary documents to remedy errors recorded on the Arrival-Departure Record at the time of entry to the U.S. relating to improper nonimmigrant classification, inaccurate biographical information or incorrect period of admission, if appropriate.
Any designated deferred inspection location or CBP office located within an international airport should be able to assist you, regardless of where the actual document was issued. In many instances, the location of your final destination where the discrepancy will be resolved may not be the port of your first arrival into the U.S. Travelers are encouraged to contact sites not located within an international airport to establish an appointment, if necessary. Mail-in procedures are not available.
Currently, there is not an approved form to request the correction of inaccurate information recorded on the I-94 or I-95 Form at the time of entry into the U.S. You will need to bring the questionable I-94 or I-95 Form and documentation to support the claim that the form was not properly annotated. For example, present a passport and visa to justify an incorrect visa classification or an approved petition to support an incorrect admission period. A fee will not be assessed.
The CBP offices within the international airports and deferred inspection locations are only authorized to correct errors that occurred at the time of arrival. Requests to replace the I-94 or I-95 Form that has been lost, stolen or mutilated must be filed with USCIS. Authorized stays that were limited at the port of first arrival by supervisory authorization as noted on the reverse side of the I-94 Form will not be corrected. Under these circumstances, you will be required to file Form I-539 with USCIS.
