Anyone that filed in February 2026 receive their receipt notice yet? Filed Feb 9th. After waiting around 21 days, I contacted an agent via emma to open a case. After around 45 days, I got an email asking me to send an email to Lockbox. Haven't heard anything from the Lockbox yet and have not received receipt yet. In the mean time, I also contacted USCIS via phone and asked for ADIT stamp. That is on the way now. Is this normal?
