读者最常问的 16 个门槛数字。每条都附官方原文逐字摘录；本站构建时逐个核对数字确实出现在摘录里，对不上就不发布。
这些数字由法律、法规或总统公告规定，可能随新规或法院裁判改变；有法院裁判影响的，在说明里写明当前状态。递交前请打开原文确认当天的数字。
H-1B 年度上限（不含高校/非营利研究机构等 cap-exempt 雇主）
“Congress set the current annual regular cap for the H-1B category at 65,000 (commonly known as the “regular cap”). ... An additional 20,000 petitions filed on behalf of beneficiaries who have earned a master’s degree or higher from a U.S. institution of higher education are exempt from the cap.”
65,000 中含最多 6,800 个为 H-1B1（智利/新加坡自贸协定）预留名额，当年未用完转入次年常规名额。

2026-06-08 联邦地区法院（D. Mass., State of California v. Mullin）撤销了执行该付款要求的机构指引；2026-07-24 第一巡回法院驳回政府暂缓执行请求；DHS 明确不同意但表示遵守法院命令，同时称若命令日后被撤销仍计划恢复征收。截至查证之日 USCIS 页面未明确说明该付款当下是否已暂停征收，请以申请当日 pay.gov 与 USCIS 页面状态为准。
