Received an interesting email from UKVI Decision Making Centre

DearXXXXX,

You have attempted to make an application for permission to stay in the United Kingdom.

The application is not yet valid. We have set out below what is missing from your application.

You must provide all of the missing information within 10 working days from the date of this e-mail otherwise your application will be rejected as invalid.

Incorrect or no fee paid

The specified fee has not been paid. You can find information on our current fees at https://www.gov.uk/skilled-worker-visa/ ... h-it-costs

The statement below provides more detail about your failure to pay the specified fee and the steps you must now take to validate your application.\

Although you have made a payment, it is not the correct amount. You must now pay the balance of £276.

You need to pay this additional fee because your sponsor’s job SOC Code is not on the Immigration Salary List, therefore, additional payment is required.

Please now follow the instructions in the guidance notes on the application form and send a completed payment slip (attached) with the balance amount. You must complete all sections of the payment slip.

Please send the completed form to: worksponsoreddocumentrequests@homeoffice.gov.uk within 10 working days quoting your application reference.

Should you wish to pay the balance of £276 by cheque please send the cheque, together with the completed payment slip to the address stated below:-

Department 600
UKVI
The Capital
Old Hall Street
Liverpool
L3 9PP

When we have received a completed valid application, we will consider it in accordance with the Immigration Rules and published policies. If you require further advice about your eligibility under the Immigration Rules, visit our website at www.gov.uk/uk-visas-immigration.

Consequences if you do not provide this information

If we do not receive your payment within 10 days of the date of this letter, even if you have already enrolled your biometrics, your application will be rejected as invalid. If your leave has expired, you will become an overstayer.

From the 18 March 2016, new fees regulations will allow the Home Office to retain an administration fee on in country charged applications that are rejected as invalid. The fee is £25 per person included in the application.

If you do not provide the payment, your application will be rejected as invalid and the Home Office will refund your fee, minus the administration fee.

If you submit a new application, the date of that application will be the date that it is posted, delivered by courier or accepted at a premium service centre.

Please note, as we have requested additional information for us to conclude your application, it may not be possible to make a decision within service standard in this instance.
*******************************************************************************************************************
I am not sure if this is genuine. I didn't know home office will ask us to pay the additional fee by requesting our card details through document. Please advise.

This is a genuine Home Office address,and you also have the option to pay by cheque.
