I've been living in the UK since November 2010 with a dependent visa, as a dependent of my wife who is a postgraduate student with Tier 4 student visa.
I've got acceptance from an Uni for a postgraduate position. About visa issue, UKBA says that I cannot switch into Tier 4 student visa and should go to my home country to apply. But University says that I can register with my current visa (but only problem is that my visa expires before course finishes and according to uni this is not a big issue and I can solve this later).
At this case, my questions is:
Must I switch into student visa or my dependent visa is enough to register and study?
If I can study with my current visa, it is perfect when consider time and money to go home and apply to new visa.

If I cannot study with my current visa, I know that I have to go home; I cannot switch here as UKBA says.

Thanks in advance
