If you move to another country and you still hold a Green Card, you must file US income tax returns as well - it's not just for citizens.

"if you are a U.S. citizen or a resident alien living outside the United States, your worldwide income is subject to U.S. income tax, regardless of where you live"

Yes, but terminating your GC status is much more easier than relinquishing your citizenship. After all, the visa is designed for that (to be something that you hold on to while in the US and give up when not maintaining permanent residency status anymore).

For sure - my comment was just referring to the often mistaken belief that a GC holder doesn't need to pay tax on income earned outside of the US.
