Hello sir,
I am currently studying in US for my Master program and my wife is applying for F1 visa for the same master program as mine. My first question is, my mother is sponsoring for my wife’s study, is it ok? Is there any additional materials I should prepare for other than the financial documents, like the proof of relationship between my wife and my mom?
My second question is, my wife only applied for one University because it is ranking high in her major and also it is the university I’m currently studying in, is it reasonable? Actually she applied for 3 universities, one in the US and another two in Canada (both universities in Canada rejected her), will it help if she mentions her application for the Canadian universities?

Thank you so much in advance!
Best regards,
Alan
