Moving to America

My family might be moving back to the United States of America.  I wonder what consequences this will have on my cycling career.  I have been trying to figure out how to make contact with the cycling authorities in America to determine what I need to do to continue cycling on my current level but so far it has been a puzzle. It looks like I am going to have to start all over and prove myself all over again.  I am afraid that I am going to miss a whole year of international competition and I am not okay with that. If anyone has any suggestions I would appreciate it.  Thanks, Chris
