Generally, the receipt notice will arrive in the mail within 3-6 weeks from the date the application was submitted.
When you apply through Boundless, our software will automatically generate a unique "@visanotify.com" email address where USCIS will send your "receipt numbers" (official codes confirming that they've received your application). This email address will be listed on Form G-1145 (officially called the "e-Notification of Application/Petition Acceptance") in your application package.
USCIS will also send a copy of the receipt numbers to you, via mail and via text message (at the phone number you provided on Form G-1145). It is important for Boundless to know when USCIS has received your application. Providing the @visanotify.com email address and your phone number therefore ensures that both you and Boundless will have a record of the receipt numbers. (For your security, Boundless does not allow external access to the @visanotify.com email account.)
Please note that USCIS will not send any other correspondence to the "@visanotify.com" email address once they have sent the receipt numbers. To receive continuous updates on your application from USCIS, you can create an account on USCIS.gov with your personal email address after receiving your receipt numbers.
