If you can managed to get a provisional booking for wedding and reception that states about the time,when and where it will be held that would be much good. Some local registrar here won't let you give provisional booking for wedding as fiancee should be here personally. Just try and explain to your local registrar y u need them. If its not possible for you to get that, you have to write a supporting letter together with your application with the background of your relationship, that u can actually support her,accomodation, also your intentions to marry her here in uk, plans for your wedding, (date,time,and location). Here is a good example of a sponsorship letter http://filipinaroses.com/showpost.ph...7&postcount=16
