i think it fair to say that if you she stayed longer than the period requested you could and should expect an interview how ever as long as you satisfy the eco or the true nature of your relationship and you satisfy all other critiria i think they would struggle to refuse,

i am sure its why they have called my fiance as they refuse a visa for my gf a different girl within the last 12 months and although i had already relised we were not right together, under those circumstances i am not surprised they want to interview my fiance,
