I was accepted into a US PhD program and then switched to the MSc due to personal reasons. After I got the MSc I wanted to continue to the PhD but then I was told that I have already graduated and was no longer a student there and I should reapply for the following term (spring 2018). So, I could no longer mantain my F1 visa status and had to leave the US.
I have written some emails to the new graduate studies director but they do not repply to me.
I want to reapply but only if I have a good chance to go back. For me it is very expensive and difficult to do so from abroad, especially for the currency exchange rate.
And as far as I know, there are top applicants from Russia and Germany. And I do not know if I will be even considered.
What should I do? How should I approach to the graduate committe?
By the way, I already passed my three PhD qualifying exams. But I stil have no replies to my emails.
