F1 visa interview issues with spouse already on F1 visa in USA

I am on my F1 visa pursuing PhD.
My wife will be taking her f1 visa interview in India. She secured a loan from Mpower(US based financing agency). She also mentioned that her spouse(me) is on F1.
Is this going to be a problem.

What are the possible questions ?
Anything we should be aware of before going to the interview.

Thanks for your time.

I do not see any issues in F1 visa interview here.
