You seem to be missing the point. As a U.S. citizen, you are eligible for scholarships any other U.S. citizen can receive. Of course, if there is a specific notation that you must graduate from a U.S.high school…that would be different.
What scholarships are you seeing that require you to live in the U.S? Please clarify.
You would not be eligible for state grant money like Calgrant and Tap…or Hope…because you don’t reside here.
But scholarships? What are you talking about where you must reside in the U.S.
In addition…you need to understand that at MANY places…if you receive an outside scholarship…it will reduce need based aid that the colleges award you. Sure…some schools allow stacking of scholarships…with need based awards…but many, many do not.
ETA…here is one of your other threads. Lots of good…and similar answers there.
