Hello there!

Yes! A Phd from a foreign university is possible after one completes his or her post graduation from a good university.

If one does post graduation from a iiser and other government colleges with good grades, one might get good scholarships as well.

Generally, one can take direct admission in the college or university in the desired Phd course.

Kindly go through the college brochures in the eligibility section before applying.

Good Luck!
