I have this same sort of question - except what if your fiancee was a student and lived with his parents? would the person just have to prove that his parents were financially able to support you if you were goin to live with them once you were married because of him being a student? thanks for your help
I'm afraid not. His parents can co-sponsor you and offer to give support or a place to live until you both get on your feet. But in the main, you and he need to be able to support yourselves fully, without recourse to public funds.
Of course, if you are getting married as soon as you arrive, you will have the option of showing how *you* can work to support the both of you.
The bit they are mostly worried about is the period between your arrival, and you being able to work. You need to show that you'll be able to support yourself for that period especially.
I hope that helps!
