Due to the COVID-19 pandemic and other factors, USCIS is experiencing delays in issuing receipt notices for some applications and petitions filed at a USCIS lockbox facility.  

As a result of COVID-19 restrictions, an increase in filings, current postal service volume and other external factors, you may experience a delay of four to six weeks in receiving your receipt notice after properly filing an application or petition with a USCIS lockbox.
