I left the U.S. to live and work in Berlin, Germany. I arrived 5 days ago. On the German side, everything is well organized, and moving along.
However until now, I hadn't reflected on which U.S. agencies, if any, I need to inform about my re-location abroad. I just found someone to take over my lease, and forwarded my mail to a relative, and left.
What U.S. agencies should I inform, if any, that I left the U.S. to live abroad?
So far all I've found is that I should inform the IRS that my address has changed -- presumably, I would provide them with my new German address, not a state-side relative's, but I'm working on confirming this.
Am I supposed to inform anyone else? It seems too easy, to just leave. Surely it's harder than this?
