Thanks alot Byang, it helps alot!

There's one thing that questioned me about this
Provisional Booking for the Wedding
Provisional Booking for Wedding Lunch
We had already talk about this to my fiance and agree some dates,register office were the wedding take place and the reception too. Do the ukvacs and eco will look for a piece of paper that stated where and when? and is it more good if he will just write it in the supporting letter?
Okay i just know now that i had to get NBI clearance, i will have do that this week then..
Hope to hear from you,
