I applied for a visit visa from the UK on the 25th of January. I printed out the biometric letter and went for biometrics, but after reaching there, I realized I missed one paper and couldn't complete my biometrics. So, I came back and tried to book another appointment, but couldn't find any available slots. Consequently, I submitted another application where I uploaded all the required documents. Regarding the biometrics, I stated that I had already provided them in 2017. Now, on the tracker, I can see that biometrics are marked as completed, but the background check is still in process for both applications. How long will it take to complete the background check?
