My brother is 15 and is very ambitious. He is in 9th grade, which is equivalent to college over here. He is very much interested I getting in an institute abroad.
The answer depends on what kind of institute you are referring to. If you are asking about US universities, then your brother would be unlikely to be accepted, though it is not impossible. If he has already graduated from high school in your country and he has an exceptional applicant profile (great extracurriculars, a high SAT/ACT, superb essays, etc.), then it would be worth it to apply and see what happens.
If you are referring to an institute as in an American boarding school, then it is very possible for your brother to get accepted. Other educational institutes, such as community colleges, would be likely to accept him as well.
Hope this helps!
