The satellites will surely have a certain amount of beam steering capability. (You need beamforming for this to work at all, I think.) If you're too far from the border, you may not be able to trick the system into believing you're in the US. (A lot depends on the implementation ... and what governments demand in terms of compliance.)

Would that be, like, one beam per connected user, or, like, city?

Per cell, size of a small city.
