How long can you stay in the UK?
This section explains how long you can stay in the UK if you successfully apply to enter or remain in the UK as the fiance(e) or prospective civil partner of a British citizen or a person settled here.
If we allow you to come to the UK in the category of fiance(e) or proposed civil partner, you will normally be given permission to stay here for 6 months. You must not work during this time.
After you have married or registered your civil partnership, you can apply for permission to remain here as the husband, wife or civil partner of a British citizen or settled person. If we approve your application, we will give you permission to live and work here for 2 years. Near the end of the 2 years, you can apply to settle here permanently if you are still married or civil partners and intend to live together
Terpe, Thank you for such a helpful link.
This was the section that set me off on the two year theme.
