(II) each other foreign state (each such state in this paragraph referred to as a "low-admission state").

(C) Determination of percentage of worldwide immigration attributable to high-admission regions. - The Attorney General shall determine the percentage of the total of the numbers determined under subparagraph (A) that are numbers for foreign states in high-admission regions.
