Sec. 301 Elimination of per-country numerical limitations
“(2) Per country levels for family-sponsored immigrants—Subject to paragraphs (3) and (4), the total number of immigrant visas made available to natives of any single foreign state or dependent area under section 203(a) in any fiscal year may not exceed 15 percent (in the case of a single foreign state) or 2 percent (in the case of a dependent area) of the total number of such visas made available under such section in that fiscal year.”
“(e) Special rules for countries at ceiling—If the total number of immigrant visas made available under section 203(a) to natives of any single foreign state or dependent area will exceed the numerical limitation specified in subsection (a)(2) in any fiscal year, the number of visas for natives of that state or area shall be allocated under section 203(a) so that, except as provided in subsection (a)(4), the proportion of the visa numbers made available under each of paragraphs (1) through (4) of section 203(a) is equal to the ratio of the total number of visas made available under the respective paragraph to the total number of visas made available under section 203(a).”
