Spouse Visa Extension Documents List 2016 - British Citizen

I got my citizenship through this route.
HSMP --> TIER1 General Extension --> ILR (2013) --> British Citizen(2014)

I need to apply for my wife spouse visa extension from uk. she has been given entry clearance as ILR Dependant Spouse (TYPE: VISA SPOUSE/ CP SPOUSE) on Dec/2013 and her visa expires on 26/08/2016

I understand that though I have British passport, my dependant should still follow the Tier1 Dependant route for thier extension. Firstly I wanted to confirm If I'm using the right application form. I'm using the below form (Tier1 or 5 PBS Dependant)

I've downloaded the form from the below url:
https://www.gov.uk/government/publicati ... -dependant

1. Is this form the right form for my scenario (Tier1 or 5 PBS Dependant)

2. Couple of queries regarding filling this form. Any help would be much appreciated

Section A
#########
2.1 - A1 - Tier1 General is the category ( is that right )

Section B
#########
2.2 - B10 - Immigration Health Surcharge ( Independent of british citizen dependant or not she has to pay for immigration health surcharge 600£ fee)

Section C
#########
2.3 - C4 - Reference no of most recent application of PBS main applicant ( That would be my british citizenship aplication reference no - is that right ?)

Section M
#########
2.4 - M1 - she is not applying at the same time as pbs main applicant that she is dependant on.
M4 - Has the pbs applicant recieved notification that thier application is successful ( I have british passport - should I chose yes or leave it blank )

2.5 - M5 - Under which category the main PBS applicant applied ( that would be Tier1- General is that right ?)

2.6 - M6 - Has the PBS main applicant's application been assessed in accordance with paragraphs 39 to 42 of the HSMP Forum Ltd Judicial review policy document ( Should I chose yes or no ?)

I need to apply for my wife spouse visa extension from uk. she has been given entry clearance as ILR Dependant Spouse (TYPE: VISA SPOUSE/ CP SPOUSE) on Dec/2013 and her visa expires on 26/08/2016

Did she apply for her visa AFTER you got ILR?

If yes, you cannot use Tier 1 Dependent. She has to apply on FLR(M) - spouse of ILR/BC visa.

Yes when she applied for Entry Clearance, she applied as ILR Dependent.

so I should be Using FLR(M) as her form for visa extension ?

Thanks.

Yes, it is FLR(M) for the extension and all the requirements have to be met again and the £500 immigration health surcharge in addition to the visa application fee which is £811 for postal and £1311 for in person same day decision.
