美国疾病控制和预防中心（CDC）宣布，基于美国国务院的请求，其行使酌情权执行“修订版命令：所有入境美国的航空旅客必须提供Covid-19阴性检测证明或Covid-19康复文件”，并立即生效。CDC做出决定认为中国上海当前的紧急情况，可能使得个人无法满足CDC检测命令修订版的要求。此酌情权的行使仅限于下列离开中国上海的个人：美国公民；美国国民，合法永久居民（LPR）; 持有有效美国移民签证的外国公民; 与美国公民或LPR同行，且持有有效旅行证件允许他们前往美国的非移民外国公民。
虽然CDC已决定所有两岁或以上的航空乘客，除了有限的豁免外，从外国登机前往美国前，必须符合检测命令修订版的要求，但是如果适用行使此酌情权的个人，无法在要求的时间范围内进行检测，航空公司可以允许该乘客在未满足 COVID-19 阴性检测或 COVID-19 康复文件要求的情况下登机。此外，根据国际和国内公共卫生建议，以及 CDC 对国际旅行和国内公共卫生的建议，个人应采取一切必要和适当的措施，在旅行期间保护自己和他人的健康，包括在飞行期间、在公共交通工具内、在机场和其他交通枢纽，佩戴贴合良好的口罩或防护面罩来遮盖口鼻。此酌情权之行使立即生效，并将于美国东部时间2022 年 5 月 11日23:59 失效，除非有所延长。
适用行使此酌情权的个人，将不需在登机前往美国前，向航空公司提供COVID-19阴性检测结果或康复文件，或完成乘客向美利坚合众国的联合披露和证明表格的第1节。
某些适用行使此酌情权的个人,例如配偶,可能是依照第10294号总统公告COVID-19疫情大流行期间推动安全恢复全球旅行，和CDC修订版命令：执行COVID-19疫情大流行期间推动安全恢复全球旅行的总统公告，所需要提供疫苗接种证明的非移民外国公民。不被视为全剂量接种可被接受的 COVID-19 疫苗的个人，可以通过向最近的美国大使馆提交例外请求，申请疫苗接种要求的人道主义或紧急豁免。如需更多信息，请访问COVID-19 信息 – 美国驻华大使馆和领事馆。

Allowing U.S. Citizens, U.S. Nationals, Lawful Permanent Residents, and their Spouses and Children Leaving Shanghai, China, to Travel to the United States Without a Pre-Departure COVID-19 Test or Documentation of Recovery through May 11, 2022
 
The Centers for Disease Control and Prevention (CDC) has announced that, based on a request from the U.S. Department of State, it is exercising its enforcement discretion regarding its “Amended Order: Requirement for Proof of Negative COVID-19 Test Result or Recovery from COVID-19 for All Airline Passengers Arriving into the United States,” effective immediately. CDC has determined that the current exigent circumstances in Shanghai, China may preclude individuals from meeting the requirements of CDC’s amended Testing Order.  This exercise of enforcement discretion is limited to the following individuals departing Shanghai, China: U.S. Citizens; U.S. Nationals, Lawful Permanent Residents (LPR); noncitizens in possession of a valid U.S. immigrant visa; and noncitizen nonimmigrants who are traveling with a U.S. citizen or LPR and possess valid travel documents allowing them to travel to the United States.
 
While CDC has determined that all air passengers two years of age or older, with limited exemptions, boarding a flight to the United States from a foreign country must meet the requirements of the amended Testing Order, if individuals subject to this exercise of enforcement discretion are not able to be tested in the timeframe required, the airlines may proceed with boarding these individuals without meeting the requirement of a negative COVID-19 test or documentation of recovery from COVID-19.  Additionally, consistent with international and domestic public health recommendations, and consistent with CDC recommendations for international travel and domestic public health recommendations, individuals should take all necessary and appropriate steps to protect the health of themselves and others during travel, including by properly wearing a well-fitting mask or respirator to keep the nose and mouth covered during the flight, as well as on public transportation and in airports and other transportation hubs. This exercise of enforcement discretion is effective immediately and will expire on May 11, 2022, at 23:59 ET, subject to any further extensions.
 
Individuals covered by this exercise of enforcement discretion will not be required to provide proof of a negative COVID-19 test result or documentation of recovery prior to boarding a flight to the United States, or to complete the attestation at Section 1 of the Combined Passenger Disclosure and Attestation to the United States of America form.
Some individuals who are subject to this enforcement discretion, such as spouses, may be noncitizen nonimmigrants who are required to show proof of vaccination under Presidential Proclamation 10294 on Advancing the Safe Resumption of Global Travel During the COVID-19 Pandemic and CDC’s Amended Order: Implementing Presidential Proclamation on Advancing the Safe Resumption of Global Travel During the COVID-19 Pandemic. Individuals who are not considered fully vaccinated with an accepted COVID-19 vaccine may apply for a humanitarian or emergency exception to the vaccination requirement by submitting an exception request to the nearest U.S. Embassy.
