Okay, please calm down. That's the very first thing you need to do. I was getting anxious too after a month and I still didn't receive my Appointment Letter. But panicking doesn't help.Yes I know but what can I do I gave my finger print I’m still waiting my interview date help me
If you refer to the DV 2018 Timelines Spreadsheets, you could see clearly that the time/duration between the Biometrics and receiving the Interview Appointment Letter varies a lot from applicant-to-applicant. So it may just be that yours is taking longer. IF you really are that worried, please schedule an INFOPASS Appointment with your closest USCIS office. That's the time when you can ask directly a USCIS Immigration Officer for a status update on your case.
