Summer activities?

So I’m a junior this year and I’ll probably go back to my home country during my last summer in high school because of a religious festival. Is it worth it to stay in the US during summer? I could potentially get an internship/do research if I stay here. If I visit my country I can get some volunteer hours and small EC stuff. Grades and scores aren’t an issue I just don’t know how to use my last summer in high school.

It is perfectly OK to go to your home country for summer vacation. This might be the last chance you have to have a break for a while.

I don’t see any reason why you shouldn’t go home over the summer. You don’t say where you are in the college search/application process, but the summer after junior year is a great time to research and think about schools, work on essays, etc. - those are things you can do anywhere.
