Answer revamped.
biochemistry is very good If you have a good academic record, especially experience in research, then I suggest you go to australia. There is scholarship that could cover the full fee for PHD candidates, and you can even apply for permanent residence if you want after you finish your program.
You can apply now if you are experienced enough.
If you are lucky to be accepted, then you can terminate your current program.. So take IELTS now,, it is not difficult,, but you need to be familiar with it..
If could you get 6.5 or higher,, then you chances of being admitted is very high..
