Issue is, this isn't boarder patrol, this is immigration control. But international airports count as the 100 miles radius as well. And things like inland ports. So this map is incorrect on enforcement for this as well.

From my understanding no the border rule stops at customs.

Yes and we have customs at international airports we also have customs at inland ports we have customs at anywhere that rail receives and rail yards distribute.

Yes but the 100 mile rule does not apply to air ports. The exception stops at the point of entry and domestic flights are exempt from the border exceptions because people do not go through customs.
