There are several answers available on Academia but all of them are 4 to 5 years old. That is why I am re-asking this question.
I was looking for a PhD in UK and contacted a professor of my interest. He's agree to take me but he said he doesn't have funding.
I searched over internet for potential funding sources but I could not find the one which is completely covering all of the expenses. There is one studentship available but it will only cover fee at home/EU rates, which are much less than international rates. Moreover, I can't apply for commonwealth scholarship.
What are other potential PhD funding sources?
Edit:
The field of study is physical sciences, physics to be exact.
