International students have a very different perspective of studying abroad. In many instances their first language is different than that of the nation they’re pursuing their education in, the culture they come from is also quite different, and the hardest part is to be able to find peers with whom you can confide in and have a normal life besides the studies that you’re obviously pursuing.
US high schools can prove to be a viable route if the goal is to go to college in the US. The reasons being you can get used to the language and the slangs that go with it, making it easier for you to fit in the college atmosphere, where every native-born is going to be following on the cultural hyperbole they were accustomed to in high school.
Another benefit of getting high school education from the US is that you have a higher chance of being able to understand American cultural concepts regarding sports and extra-curricular activities as high school is the formative time period for every American kid, and you won't be far off from them if you gather that experience.
Finally, you'll be able to apply for colleges with much higher chances of getting admitted as you'll be applying within the system and you'll have a better idea of how to navigate and know which colleges are best suited to you.
