Getting braces in Foreign country and have check up in US?

I'm an international student, and I'm currently having my summer vacation in my hometown. I wanna take this gap and get braces in my country, so that I have enough time to get used to them until I come back to US and continue my study. The thing that I'm wondering is that whether the orthodontists here in America will help me tighten the braces when I didn't get the braces from them? If they do, can the dental insurance cover part of the cost?

over here they should be able to help tighten them but if the ones you are getting are old ones i am not sure but they should and i think the insurance should help cover some of the cost they do for mine.
