Does Biometrics / actual Visa stamping also need to happen within 3 months of endorsement email?

Thank you! I was getting worried coz I saw some Stage 2 discussions on our forum where TB reports were taking more than 2-3 months such as these:

  1. Hello, i did my tb test march and i was asked to carry out a sputum test which will take about 10 weeks. My CoS expires in a week time, but I've paid my visa fee, but haven't booked a date for my biometrics. Hope this won't backfire? Any suggestions?
  2. TB certificate delayed and required submission
