Currently, the average processing time for an I-526 petition ranges from 20.5 to 27 months, as shown in the screenshot from USCIS website below. For cases filed with an receipt date of January 29, 2017 or earlier that remain pending with USCIS, the investors or the attorneys of record can submit an “outside normal processing time” service request online or follow up with the Immigrant Investor Program office at USCIS.
