I think I made a big mistake on presuming that I can change my fiancè visa on spouse visa once I get in Uk I have confused the rules and having not understood of which and which situation it applies.
As I re-read it again twenty times or more today and consulting my fiancè we have come to a conclusion that there might be changes that we need to undergo with

.
We have this four options:
1. Cancell marriage here in Italy-get my fiancè visa and marry in UK and switch in spouse visa? (wedding stuffs and everything is already settled!!!)
2. Marry in Italy-marry again in uk and get spouse visa? (is it allowed and if yes what is the difference?)
3. Marry in Italy and apply in Italy?

I am confuse at the moment!
