Suspending the Right to Introduce Certain Persons from Countries Where a Quarantinable Communicable Disease Exists
During the COVID-19 pandemic, CDC issued a series of orders under 42 U.S.C. §§ 265, 268 and 42 C.F.R. § 71.40 suspending the right to introduce certain noncitizens attempting to enter the U.S. from Canada or Mexico (regardless of country of origin) at or between ports of entry. The initial Order Suspending Introduction of Certain Persons from Countries where a Communicable Disease Exists was issued by CDC on March 20, 2020.
The Order was replaced with the Order Suspending the Right to Introduce Certain Persons from Countries Where a Quarantinable Communicable Disease Exists on October 13, 2020. Unaccompanied noncitizen children (UC) were subsequently excepted from the Order. On August 2, 2021, CDC replaced previous the Order. UC continued to be excepted from application of the Order and CDC permanently terminated the Order with respect to UC in March 2022.
On April 6, 2022, following a public health determination, the CDC Director announced her decision to terminate the August 2021 Order suspending the right to introduce certain persons into the United States. Due to a court injunction, however, the termination could not take effect and the August 2021 Order remained in effect until May 2023.
The COVID-19 Public Health Emergency expired at 11:59 pm EDT on May 11, 2023. By its terms, the Order issued in August 2021 terminated upon the expiration of the public health emergency.

Implementing Presidential Proclamation on Safe Resumption of Global Travel During the COVID-19 Pandemic
On October 25, 2021, the President issued a Proclamation for the resumption of global travel and implemented a global suspension and restriction on entry for non-U.S. citizens who were nonimmigrants seeking to enter the United States by air travel and who were not fully vaccinated against COVID-19 as defined at the time. The Proclamation directed CDC to implement the Proclamation as it applied to the public's health in accordance with appropriate public health protocols and consistent with CDC's independent public health judgment.
Therefore, CDC issued an Order on October 25, 2021 (later amended on October 30, 2022) to implement the President's direction. The Order implementing the Presidential Proclamation was effective November 8, 2021.
On April 4, 2022, CDC amended its October 30, 2021, Order to align post-arrival public health requirements for self-quarantine and self-isolation for noncitizen nonimmigrants who met an exception to the proof of vaccination requirement with recommendations in place at the time for actions to take after international travel. The Amended Order also formalized guidance described in Technical Instructions, announced in FAQs on CDC's website, and in the attestation. The Amended Order went into effect for flights departing to the U.S. from a foreign country on April 14, 2022.
Beginning 12:01 a.m. EDT on May 12, 2023, the Amended Order ceased to be in effect. Noncitizen nonimmigrant air passengers no longer needed to show proof of being fully vaccinated with an accepted COVID-19 vaccine to board a flight to the United States.

Framework for Conditional Sailing Order for Cruise Ships
On October 30, 2020, CDC issued a Framework for Conditional Sailing Order (CSO). The Order established a framework of actionable items for the cruise line industry to follow so they could resume passenger operations with an emphasis on preventing the further spread of COVID-19 on cruise ships and from cruise ships into communities, and to protect public health and safety. The first phase of the CSO involved establishing laboratory capacity both on board ships and at shoreside facilities for COVID-19 viral testing using nucleic acid amplification tests.
On April 2, 2021, CDC released a new phase of the CSO for cruise ships operating or seeking to operate in U.S. waters. This new phase required cruise lines to establish agreements at ports where they intended to operate, implement routine testing of crew, and develop plans incorporating vaccination strategies to reduce the risk of introduction and spread of COVID-19 by crew and passengers.
On May 5, 2021, CDC released the next two phases of the CSO for cruise ships operating or seeking to operate in U.S. waters. With the issuance of the next two phases, cruise ship operators had all the necessary requirements and recommendations they needed before resuming restricted passenger voyages as defined by the CSO.
On October 25, 2021, CDC extended the CSO with minor modifications.
On January 15, 2022, the CSO expired. At that point, CDC transitioned to a voluntary program, in coordination with the cruise ship operators and other stakeholders, to assist the cruise industry to continue to detect, mitigate, and control the spread of COVID-19 onboard cruise ships. The voluntary program formally ended on July 16, 2022, although CDC continued to issue guidance.
