I just came across an interesting question. Somebody suggested that I
should move to an island in Micronesia and accept a job there. Many of the
islands there have special relationships with the US, and to make things
more complicated, the status of each island is different from its
neighbor.

Now my question: if I moved to one of these islands, would that be
considered leaving the United States, would I be giving up my Green Card?
If not, would the time spent there count as "physically presence" for
naturalization purposes?

Here are the islands in question, and I'd appreciate any opinions on how
safe or unsafe it would be (in terms of retaining GC and naturalization)
to move there.

Guam: that's easy, it's a US possession and treated the same as Puerto
Rico or the mainland.

Saipan/Tinian/Rota (Northern Mariana Islands): These are a US
"Commonwealth" and are semi-independent. I believe US immigration laws
were only recently introduced there; they used to have their own rules.

Ponope/Truk (Federated States of Micronesia, I believe). I don't know
their status.

Palau: I believe this is a completely independent country, so the answer
is fairly simple again.

Thank you very much!
