Biometric request is an auto generated request, the logic is designed in the back endI applied for a visitor visa for my in-laws (India) on September 19th via the new portal and today on 22nd September we received a request for biometrics. I think, it’s totally dependent on the officers who are working on your case and also the travel history. I know, we haven’t received the PPR request yet but I am hoping to hear something soon.
For example if you had applied in the 10 last years for some other application and provided your biometric. Now if you are using the same login (GCkey) you won’t get a biometric request. Hope I am making sense.
