You express yourself so unclearly that I don't quite understand your statement - but I suspect that you are wrong.
Your statement that "only 'states' get Constitutional protection that 'states' get" is, of course, a tautology, and hence pretty useless.
Territories do, of course, exercise a limited form of self-government - it is thus ridiculous to assert that they are "run like a separate country."
I don't understand what you mean by "territories [having] US residency." A territory cannot "have" residency.
Regards,
With all but one of our US territories, only portions of our US Constitution apply to each.

Only states get all the protection and expectations of our Federal government.
Im always glad to teach the Constitution to others!
