Hello,

Yes, after doing BS-MS from IISER, you can go abroad for a PhD. You need to apply yourself to foreign universities. Many universities require exams like GRE and TOEFL/IELTS.

Some IISERs offer support through recommendation letters, research experience, and guidance. There are also scholarships like Fulbright, DAAD, and university-specific funding.

IISER itself may not provide a direct scholarship for a PhD abroad, but research internships and fellowships during BS-MS can help strengthen your application.

Hope it helps !
