I am in UK on Tier 2 General Visa and my wife got Tier 2 dependent visa. We have blessed with a baby recently and i want to know how to apply for baby visa. could you please advise on following
Which form I have to fill in (i guess i have to fill on her behalf ...she can't type

I would be able to apply for ILR in 2019 so do i need to pay for baby's health surcharge for the next 3 years i.e.£600 or I can pay for next 2 years during which I will get my ILR and she will get citizenship. can i save £200 for an extra year?
Do i still need to show maintenance fund for her application??
many thanks in advance
