Back to your questions - what do I do?
You have two choices:
-
Get engaged in a hobby or two - walk dogs at the shelter, play sports, get a job, join a club at school or do something of interest in the community if you want to enhance your out of school profile.
-
At application time - and #1 doesn’t really impact this, ensure you apply to a school that you can get into and can afford. If your ECs aren’t robust, there will be plenty of fine schools that will love to have your money. Note - many a state flagship (very good ones) don’t care if you have ECs at all - and many private schools as well.
Best of luck.
That’s really the answer to your thread - forgetting visa issues and other things such as careers.
Best of luck.
