When you say "living abroad", do you mean you have a local job, get paid in the local currency, pay rent and bills in the local currency, etc.? Which you do all through a US bank? If so, what are you paying for international transaction fees? Surely much more than using a local debit card.

There's nothing special about the US in that regard. A citizen of Germany can do the same at any German embassy, even when not a resident in Germany and therefore not paying German income taxes, and also has the right to return to Germany.
