hey! it depends entirely on the case. I’ve seen some people wait 6 months for biometrics. me personally I applied within the USA July 11th 2023 and my biometrics was Scheduled August 7th of 2022 so just a little under a month. however that depends entirely on where you’re applying from (if you’re in the USA or abroad it will be different)

I’m in USA. I applied June 23

I recently saw a similar post about this so I'm not sure if this is becoming a thing with USCIS.
