First, 7th grade is WAAYYYYY too early to even think about thinking about college. The kid is what, 13? Who know what they will want next year, much less four or five years from now?
My kid changed a lot from 7th to 8th grade, and even more drastically when she started high school. By the time she started looking at colleges between 10th and 11th grade, she had changed again. Her interests, her idea of life, who she felt that she was, were radically different when she was applying to college from what they were in 7th grade.
Let your kid be a kid. They only get a few years to be a kid, and it is cruel to have them waste their kid time on pursuing things that may or may not help them as adults.
At this point in their 7th grade, your kid should be thinking about high school, and how to make use 8th grade to help them move on to high school.
If, by the beginning of 9th grade, your kid is still yearning after the USA “college experience”, that may require a bit more early planning than if your kid was being raised in the USA. However, that also requires that USA college life still be interesting for him, at that point.
Until then, middle school sucks enough, and there is no reason to add stress and pressure on the kid about what they may have to do sometime in the future, in order to achieve a goal that is even farther in the future.
