I am sorting references for the above bits still. But for your comment...
You will be allowed to stay in the UK for six months but without permission to work. When you are married or have registered a civil partnership, you can apply for a two-year extension to your visa and, if your application is granted, you will be allowed to work. Near the end of this time, you can apply to stay in the UK permanently. Before we can give you permission to stay in the UK permanently, you will need to pass the 'Life in the UK' test.I am wrong in wording this as ILR, it should be FLR.Q. What do I need to do after I am married to a UK citizen?
A. You must apply for your Further Leave To Remain visa from the Home Office.
(Think to yourself, what do you do after the 6 month fiance visa is over?)
