FLR(M) form 4/2018 questions.

[Chanan17]

Hello, This is my wife first visa application on form FLR(M) in the UK after
entry clearance as a spouse/cp of husband for 2 years 9 months.
We have a appointment for a premium service location soon
next month.

I have some question if someone can help me.

I worried for her employer only send her pay slip by email
so I have to print them off myself.
Q. Is email print off payslip OK with a manager letter to go
with them? ( they have no stamp either to stamp them)

Section 4 page15 Dependent children.
In this section you must include any dependent children that are applying with you.
WE HAVE NO CHILDREN APPLYING WITH HER.
Then it says you should also include details of any dependent children NOT
applying with you.
I have 3 sons in the UK 36,37, & 42 so I don't think I should put them down.
My wife has 2 daughters still in her home country 16 & 19.
Q. Should any be put in the form or just the 16 year old. ( she is still at school
but has a part time job so she is not totally dependent )??

Financial requirement
If we have a problems with her pay slip/manager letter. I am thinking about using
cash saving I have put aside for this just in case.
Q. Is it mandatory to fill/complete page 27,28,29,30,31,32 & 33 with income/
pension etc. If we want to use cash saving alone?

Sorry it is a bit long
Many thanks
