On ILR n applying for wife's visa from chennai

[jlkjoy]

Hi,
My name is Laxmikant. I am residing in UK under indefinite leave to remain visa status/ permanent residency (PR).
I am getting married in October this year.
I have to apply for my fiancée' visa.
I need your valuable suggestions regarding the documentation process towards her dependent visa, which would be greatly appreciated.
What is the current processing time if applied through VFS chennai?
Does the one day premium service applicable to dependent visa?
Many Thanks,

[vinny]
