Location of Tier 1 (General) Application Processing Centre

[nnj10]

I have recently applied for my Extension of (HSMP) Leave under Tier-1 (General), which I sent at the following postal address:

UK Border Agency
Tier 1
PO Box 496
Durham
DH99 1WQ

I have received a letter with the reference number today, and on the envelope the return address is

UKBA (Charging Ops Team)
PO BOX 3468
Sheffield
S3 8WA

Where as it is sent by (as shown on the letter, which is not signed)
UK Border agency
North East, Yorkshire and the Humber Region

Does H.O. move the file from Durham to Sheffield?
Is the case worker based in Durham/Sheffield or Croydon?
I paid for my application by credit card, which is billed as
"Home Office Croydon"

Can any one who has received the documents back from HO please confirm me whether they received the documents back from Durham/Sheffield or Croydon?

All the details you mentioned above are CORRECT n same in my case aswell... So do not worry

only difference is i paid by Debit card....

Do not worry too much since you got the REference No which you can always refer incase of any problems to track,,, and you might have also got the some details that the payment has been proessed and cleared and that your applcation will be passed to a caseworking team for validation and cosideration... etc,

Goodluck
