There are some downsides of transferring high school half way through. As one example, when you apply to universities, you will need to send in references. If you stay at the same high school for a full four years this will give people there (eg, teachers and guidance counselors) time to get to know you. Similarly your ECs could be interrupted to some extent if you change high school half way through.
I am wondering if you will just need to wait until you go to university, which of course is very often a “live on campus” experience.
We have also had some good experience with study abroad, even in high school. You might want to see whether your current high school has a program where you get to go to some other country for a short time (sometimes for one semester, for example).
