I will share a recent example of my friend who came here last month. His background is completely different than what he wants to study. I kept on advising him to look for a program that will match with his background but he was not convinced that he wants to spend money in something that he has already studied and no longer interested in making a career in that field. And i was very convinced that he wont get an approval unless he finds a program matching his background. To my surprise, he got help from somebody and got the visa
. i am not very qualified to advice on the details but I have sent you a link about a law or whatever they call it in the legal field which was used in his reapplication. check that. It may help you.
