Just so we're clear: if your legal duty is to appear in person to register every six months, that won't change absent some sort of waiver. Even if you think flying back is "nuts." If your legal duty is to appear in person, and you fail to do so even because you've moved abroad, you will still be committing a felony.
What you do is you continue to comply with your legal duties in America. Your duties to America don't end because you've moved abroad.
BTW, I'm dying to know what country you're talking about. Is it too much to ask that you share it?
