更改

因为 USCIS 的流程和数据完全不透明，在2015年，引入了 A / B 表的制度，其本意是为了让 USCIS 的流程更接近 DOS 的，也就是先按照一定的提前量收表（B表），这样可以准确知道 I-485 库存的 国家 和 Priority Date，以此可以让排期更准确。

这是史上第二次修改排期表（第一次是 [[07大潮]]）。 这一事件引发了所谓 Visagate，或者“签证门”诉讼。诉讼的结果是，法院判决，排期表在下月生效以前，不能认为是最终版。国务院有权在生效前做出改变。<blockquote>The two Visa Bulletins are not "definitive statements" but informative statements; the September 9, 2015, Visa Bulletin did appear to have a direct and immediate effect on the day-to-day business of Plaintiffs; the Visa Bulletins did not have the status of law, if at all, until October 1, 2015; immediate compliance with the terms of these Visa Bulletins was clearly not expected; and the Visa Bulletins did not necessarily answer a legal question. These indicia of finality support the Court's conclusion that the two Visa Bulletins in question do not constitute final agency action.</blockquote>随着第一次引入 AB表 导致的闹剧，USCIS 在随后并没有一直使用 B表。在 2017年1月 更换总统以后，更出现了2018财年全年不适用 B表 的情况。这个半吊子的项目，目前只剩下了仍然在 DOS 网站挂着的那句“USCIS, in coordination with Department of State (DOS), is revising the procedures for determining visa availability for applicants waiting to file for employment-based or family-sponsored preference adjustment of status. The revised process will better align with procedures DOS uses for foreign nationals who seek to become U.S. permanent residents by applying for immigrant visas at U.S. consulates and embassies abroad.”
