Electrical Engineering

Dear Harika!
I don't understand that for which problem you are talking about. I think that you are afraid of the change in the stream from electrical to computers. Right? So dear, I want to clarify that there is no harm in changing the stream from UG to PG. You are absolutely eligible (provided you must have to fulfill other conditions also). However, your visa investigation officer may ask about this question. And trust me, you must have to convince him with your answer. You may face this (that why you want to change your stream?) in US's university application form. So be prepared for the answer. Otherwise, all is well.
Kindly upvote the answer if you are satisfied.
Ask any query anytime!
Good wishes!
