Hi Passportwait,
It looks like you are joining the unlucky ‘Processing’ group. From what I can tell if you are lucky then your application goes straight from ‘Documents received’ to ‘Application approved’ in about a week.
If your application is in ‘Processing’ it is waiting for a physical exam from an examiner, this wait can take anywhere from 5-10 weeks from the date they received it in Durham.
Here my timeline for reference:
Application submitted: 17 Feb 2022
Passport recieved at Peterborough (via Royal mail tracked): 18 Feb 2022
Documents Received: 28 Feb 2022
Documents sent to Durham: 3 March 2022
Application being processed/waiting for examiner: 11 March 2022
