[tycouk]

Hello all senior members and dear members,
I have a question regarding the visit visa to mother-in-law.
I have applied for British passport 2 days ago and planing to apply the visit visa to mother-in-law.
I have not surrender my Indian passport yet as it will take 4-6 weeks min to get the British passport.
may i know which supporting document i need to show from my side, do i still show ILR on Indian passport or ceremony certificate is good enough.
please suggest me.
Thanks all in advance and looking forward for some suggestions.

Cheers
