Update on Submitting Immigration Approvals
When applying to update the I-171H/I-797C, families must also submit their home study update. Families are NOT permitted to submit a request to update the I-171H/I-797C separate from their home study update. All documents must be submitted at the same time. This is the case for families using the I-600A or I-800A application.
Beginning September 25, 2008, families will no longer submit I-800A applications to their local USCIS office. Instead, families must submit an I-800A and accompanying documents to the following location:
For USPS mail:
USCIS
PO Box 805695
Chicago, IL 60680-4118
All non-USPS mail:
Attn: Hague
131 South Dearborn
Third floor
Chicago, IL 60603-5517
Families submitting an I-600A application will continue to submit this form to their local USCIS office. Please click on the following link to find your local USCIS office: https://egov.uscis.gov/crisgwi/go?action=offices.type&OfficeLocator.office_type=LO
