My VISA was granted on 26 Jul 2006, I arrived in UK on 27 Aug 2006.
My appointment was 11:15. I arrived 20 minutes earlier and my token number was called on 12:15.
the doc were asked by case worker:
SET O form,
Passports
3 months payslips
3 months bankstatment
Employee letter.
Case worker told me I submitted application a bit early and it should be 28 days before 27 Aug 2011. I showed him the new guidance that changed in April. He talked to his colleague then came back said its ok.
An hour later he completed the input and paperwork and told me my application was successful and go to counter 22 to collect passports in an hour.
I had lunch in the nearby town centre and came back to see ILR has been granted.
