That is up to the country you are transferring through. In the US, for
instance, you need to go through imigration even when you are transferring
between two international flights.

I suggest the following Wikipedia article as a good starting point:

No, but I think admin_level should indicate that a line is a boundary
between two entities of the same level. When you say that a boundary is
admin_level 2, does that not indicate that you have one country on one side
of the line and another country on the other side of the line? If used on
maritime borders of 12 nm, it indicates that you have one country's
territorial waters on one side and the contiguous zone of the same country
on the other side. If used at 24 nm it indicates one contry's contiguos zone
on one side and the same country's economic zone on the other side.
