BITS Pilani accepts international students who have attempted SAT.

NIT Trichy will be difficult to get especially for CSE. The required cutoff is quite high for NIT Trichy. However, you can still apply for the program and if you are lucky you may get chosen. Generally, it is difficult because NIT Trichy is considered as one of the best NIT’s and it ranks over many IIT’s. You can also go through Google’s “DASA program in India” for admissions in other branches in different NIT’s.
