My wife, who is Japanese, has been advised that to apply for a marriage visa could take a long time before it is awarded. From the research I've done, I understand that it's not possible to change your visa status whilst in the UK. Eg - from a tourist visa to a marriage visa.
We were wondering though, whether my wife could apply in Japan and come over on a tourist visa while she waits for it to be granted. Personally, I don't think this is possible but she's been told so many conflicting things by the British Embassy that we don't know what to believe now!

Any helpful advice would be appreciated.
