Re-apply the PhD program that I previously got offer and turned down My situation is as follows:


I applied to PhD program A and B, and got offers from both.
However, the offer of A came too late which was after the deadline of decision for B. So I took offer B, and got the offer A one day after accepting B.
At that time I struggled a bit, and decided not to turned down B because I thought there were an ethical issue.
Now I am about to start the second year PhD at B, but I don't feel like this is the appropriate university to continue my study. So I am thinking about re-applying A and drop B.


My question is that in my case, is it possible to simply do a transfer from B to A and continue my PhD, instead of dropping B and re-applying A, or is there another way which is simpler than re-applying?

Also, do graduate programs allow one to apply PhD programs while studying one? These questions all depends, I guess, but I wonder if there are general cases.
To transfer means that you will need to find a new supervisor who is prepared to take you and your project on in the current state.

That might be a challenge and a bigger challenge than you realise, it is not just walk out the front door of B and in through the front door of A...
