I am an undergraduate student looking forward to applying for a Master or preferably a direct Ph.D. program for Fall 2019. My undergraduate degree is in physics and I want to study data science or applied mathematics or a master in statistical physics (In order to change to data science for a Ph.D.).
I will be recognized as an international student in North America and Europe and I have scored 7.0 in the IELTS exam and my GPA is 3.6 out of 4 and I have publications.
I most certainly need a fully funded scholarship/fellowship to cover my tuition fee and living expenses and that's the top priority for me.
(I found the answer here helpful)
A) My first question is which region is, in general, better for my application request?
Given the fact, I should also take the GRE test (Which is very expensive for me in my country) for the US and Canada but they offer direct Ph.D. programs.
B) My second question is what I have noticed while emailing the professors.
US professors which have replied to my email positively have stated that they take new direct Ph.D. students in research groups but I must first be admitted to the university. Is there a way I make sure if I am admitted I will receive this funding?
Can US professors affect the results of the admission process in any way? Like by directly accepting a student? if so how can I ask for it without being rude? What about EU or Canada?
