Hey Paarth

I have a few recommendations regarding foreign universities for your brother in 9th class.

Those looking to pursue higher studies from abroad, generally prefer going to the USA. For that you need to give TOEFL or IELTS  .You will need a good SAT Score , Statement of Purpose  / Essay  , Letters of Recommendations and Educational documents (college and school certificates).

So I will recommend you to start working on these. All the best.
