国务院 26 日通告，中国、伊朗、巴西、南非、申根地区、英国、爱尔兰等地的 F-1/M-1 学生和交换学者，符合「国家利益豁免」；来自中国的 F-1/M-1 留学生，若开学日期在 8 月 1 日之后，可提前不超过 30 天入境美国。如果已有签证，无需单独联系使馆，可直接入境美国；无签证则需联系当地使馆。
去年 Covid-19 疫情开始后，川普总体发布禁令，除绿卡、公民及其亲属等部分例外类别外，14 天内到过中国大陆的旅客禁止入境美国，意味着来自中国大陆的 F/M/B 等签证，需要到第三国洗白 14 天方可入境美国。本次通告仅包括 F-1/M-1，未包括 F-2/M-2 以及 B1/B2 。通告如下。
On April 26, 2021, the Secretary of State made a national interest determination regarding categories of travelers eligible for exceptions under Presidential Proclamations (PPs) 9984, 9992, and 10143 related to the spread of COVID-19. As a result of this determination, together with national interest determinations already in place, travelers subject to these proclamations, due to their presence in China, Iran, Brazil, South Africa, the Schengen area, the United Kingdom, and Ireland, who are seeking to provide vital support for critical infrastructure; journalists; students and certain academics covered by exchange visitor programs, may now qualify for a National Interest Exception (NIE). Students and academics subject to these proclamations due to their presence in China, Iran, Brazil, or South Africa, may qualify for an NIE only if their academic program begins August 1, 2021 or later. Qualified travelers who are applying for or have valid visas or ESTA authorization may travel to the United States following the procedures below, even as PPs 9984, 9992, and 10143 remain in effect.
Students with valid F-1 and M-1 visas intending to begin or continue an academic program commencing August 1, 2021 or later do not need to contact an embassy or consulate to seek an individual NIE to travel. They may enter the United States no earlier than 30 days before the start of their academic studies. Students seeking to apply for new F-1 or M-1 visas should check the status of visa services at the nearest embassy or consulate; those applicants who are found to be otherwise qualified for an F-1 or M-1 visa will automatically be considered for an NIE to travel.
Travelers in categories described above who have a valid visa in the appropriate class or who have a valid ESTA authorization for travel under the Visa Waiver Program and seek to travel for purposes consistent with ESTA authorization, should contact the nearest U.S. embassy or consulate before traveling, if they believe they may qualify for a National Interest Exception. If a National Interest Exception is approved, they may travel on either a valid visa or ESTA authorization, as appropriate.
The Department of State also continues to grant NIEs for qualified travelers seeking to enter the United States for purposes related to humanitarian travel, public health response, and national security. These travelers and any others who believe their travel to be in the United States’ national interest should also review the website of the nearest U.S. embassy or consulate for instruction on how to contact them.
