USCIS Continuing Form I-751 Data Entry

From USCIS:

USCIS has completed receipting and data entry for all filings of Form I-751, Petition to Remove Conditions on Residence, received between May 1 and Sept. 9, 2018. Petitioners should receive receipt notices by Oct. 22, 2018. On June 13, 2018, USCIS announced that the California Service Center (CSC) was experiencing a delay in initial data entry for Form I-751. After changing the filing location for Form I-751 from the USCIS Service Centers to the USCIS Lockbox facilities in September, USCIS completed receipting and data entry of these petitions on Oct. 1. If you submitted a Form I-751 to the CSC between May 1 and Sept. 9, 2018, and you have not received a receipt notice, do not file a duplicate Form I-751 unless you have received a rejection notice or have been instructed to do so by the CSC. If your two-year green card has expired and you have not received a receipt notice, you may schedule an appointment online for you and any eligible dependents to be seen at your local field office. If possible, bring evidence that you sent your Form I-751 via the U.S. Postal Service or a delivery service, such as FedEx. If you have any questions about the process, visit the USCIS Contact Center page.
