You show residency when you live in a location and register to vote. If you move overseas, you remain registered in the county/precinct where you were last a resident.
You then vote in elections. I've got my ballot for the November elections, ready whenever I am.
And as for taxes, If you live in a higher tax location, you're not going to pay anything to the US. If you earn under 100k, you aren't going to pay anything in the US. You do have to file a return tho, which is a pain.
