If you want more fun info: if you move abroad you still owe Medicare & Medicaid, the national healthcare plan. Neither of these can you get an tax exemption, reimbursement, or a voucher to use in another country even if you haven’t stepped foot on US territory in decades. You will pay into these services your whole life if you have a passport to that shitty system & never get anything in return unless you fly to the US to have a procedure that will cost more than it does in the country you might be living in (even without insurance).

During COVID when Sleepy Joe Biden promised vaccines for all Americans that want vaccines, the health minister had to step in when asked to clarify that historically the US does not help its citizens abroad & to go ask the host country instead--or to get on a plane, in a pandemic, quarantining both ways, if you want a shot. The cherry on top was sending vaccines aboard for political favors & if you asked if the embassy if any of those will be used for citizens abroad to be told these were for diplomatic purposes only (meanwhile France & China sent its citizens shots).
