Boarding School Hurts You?

Can anyone also weigh in on the geographic diversity factor and Boarding School. Let’s say your from Montana and go to a NE boarding school. When you apply to college, will you then be considered as a student from Montana (home state ) or a student from Academy X from NE :)? Second scenario can be if you’re from a place with a great in-state university system ( Virginia, California, Michigan, U of You, etc)… You can go to BS come back to your home state as a competitive student and get in-state tuition. That happened to our nephew who had a great BS experience and then got great tuition $$$ package at a UC school :)…, just saying because he was FA for both.
