SEC. 104. LIMITATION ON PER COUNTRY CEILING WITH RESPECT TO EMPLOYMENT-BASED IMMIGRANTS.
翻译：对工作移民数额国别上限适用性的限制。
所谓工作移民，或"employment- based immigrants"，指的是试图通过在美国工作取得绿卡的这群人，h1b转绿卡是其中一个子集，在这一子集中大部分人使用的是EB2子项。来自中国和印度两个移民大国的申请者极多，受到按国别的数额上限限制而必须排期。104节标题中写的“per country ceiling”指的就是这个上限，这一节规定的是配额上限在某些情况下可以暂时免除，所以叫做对该上限的限制（limitation）。
该节的(c)(2)款写到：
“ONE-TIME PROTECTION UNDER PER COUNTRY CEILING- Notwithstanding section 214(g)(4) of the Immigration and Nationality Act (8 U.S.C. 1184(g)(4)), any alien who is eligible to be granted that status but for application of the per country limitations applicable to immigrants under those paragraphs, may apply for, and the Attorney General may grant, an extension of such nonimmigrant status until the alien’s application for adjustment of status has been processed and a decision made there on. ”
“In the case of a nonimmigrant described in section 101(a)(15)(H)(i)(b), the period of authorized admission as such a nonimmigrant may not exceed 6 years.”
(b) EXTENSION OF H-1B WORKER STATUS- The Attorney General shall extend the stay of an alien who qualifies for an exemption under subsection (a) in one-year increments until such time as a final decision is made on the alien’s lawful permanent residence.
(a) EXEMPTION FROM LIMITATION- The limitation contained in section 214(g)(4) of the Immigration and Nationality Act (8 U.S.C. 1184(g)(4)) with respect to the duration of authorized stay shall not apply to any nonimmigrant alien previously issued a visa or otherwise provided nonimmigrant status under section 101(a)(15)(H)(i)(b) of that Act on whose behalf a petition under section 204(b) of that Act to accord the alien immigrant status under section 203(b) of that Act, or an application for adjustment of status under section 245 of that Act to accord the alien status under such section 203(b), has been filed, if 365 days or more have elapsed since--
(1) the filing of a labor certification application on the alien’s behalf (if such certification is required for the alien to obtain status under such section 203(b)); or
(2) the filing of the petition under such section 204(b).
