The federal agency said that the Secure Mail Initiative (SMI) has been implemented and it will utilize US Postal Service (USPS) Priority Mail with Delivery Confirmation. This change will ensure that immigration documents are not only delivered in a secure fashion but also that they arrive in a timely manner, according to the USCIS.
SMI will allow those waiting for important immigration ins documents – such as permanent residence cards and employment authorizations – to track their packages using the Post Office's tracking system. It will also get these US green cards and other documents to their intended recipients. According to a release from the USCIS, post sent as USPS Priority Mail usually arrives two to four days sooner than first-class mail.
The USCIS said in its release that those waiting for immigration documents should wait at least two weeks after they get their approval notices to contact the agency for further information.
