USCIS has released the following press release regarding secure mailing beginning April 30, 2018:
U.S. Citizenship and Immigration Services (USCIS) announced today that the agency will begin phasing in use of the U.S. Postal Service’s (USPS) Signature Confirmation Restricted Delivery service to mail Green Cards and other secure documents beginning April 30, 2018.
The first phase will affect documents that need to be re-mailed because they have been returned as non-deliverable. These documents include Permanent Resident Cards (also called Green Cards), Employment Authorization Cards, and Travel Booklets. Applicants who have changed mailing addresses during the course of the application process are more likely to have their secure documents sent with the new delivery method, which USCIS will expand to all secure documents in the future.
As part of the new delivery method, applicants must present identification to sign for their documents upon delivery. They also have the option to designate an agent to sign on their behalf by completing the Postal Service’s PS Form 3801, Standing Delivery Order (PDF) or PS Form 3801-A, Agreement by a Hotel, Apartment House, or the Like (PDF). Applicants can sign up for USPS Informed Delivery to receive delivery status notifications. Applicants will also have the option to arrange for pickup at a post office at a convenient date and time by going to the USPS website and selecting “hold for pickup.”
