Change in Major for MS - affect in F1 visa

Hi. I have done my undergraduation in AERONAUTICAL dept. Now i want to change to Computer science stream. I already got admission for CS. Attended Visa interview. But rejected. I booked another slot on July 29th. What can be the most convincing answer to VO for changing branch ? Looking for valuable suggestions. TIA.

Well, Did the visa office indicate why you got rejected ? Visa stamping can always be tricky…sometimes, even though you give your best shot, luck plays a factor as we have no idea whats going on in the VO mind.

All I can suggest is that, be honest and explain your reasons for applying to CS and changing major. Nothing beats passion for change and learning. Dont try to fabricate something, just stay strong and give your honest answers and trust it will work out.
