U.S. Citizenship and Immigration Services (USCIS) has fully implemented the Secure Mail Initiative (SMI), which uses U.S. Postal Service (USPS) Priority Mail with Delivery Confirmation to deliver certain immigration documents in a safe, secure and timely manner.

The SMI enables USCIS to confirm delivery of permanent resident cards and documents pertaining to travel and employment authorization. With

USPS tracking information, USCIS customers can also stay up-to-date on the delivery status of their documents.

SMI provides USCIS customers many benefits, including the ability to track the status of their documents with USPS tracking information and quicker delivery—on average, documents sent through USPS Priority Mail should arrive two to four business days sooner than with first-class mail.

Customers who receive notices of approval can contact USCIS’ Customer Service Center at 800-375-5283 to request tracking information for their documents. USCIS customer service representatives will provide customers with their USPS tracking number and current USPS delivery status. USCIS advises customers to wait at least two weeks after getting their approval notice before calling for information regarding their cases.
