On January 27, 2017, President Trump signed an executive order entitled “Protecting the Nation from Foreign Terrorist Entry into the United States.” This executive order called for an immediate halt to entry for any immigrant or nonimmigrant from Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen, as well as an immediate 120-day halt to all entries by refugees and an indefinite suspension with respect to Syrian refugees. Many individuals who were in the air at the time the executive order was signed were detained by CBP upon arrival in the United States, including lawful permanent residents and individuals with valid visas for entry.
Individuals detained by CBP were held for extremely long times (over 24 hours in some cases), denied access to their families, prevented from talking to attorneys, and on some occasions pressured into signing documents renouncing their right to enter the United States and forcibly deported. Large numbers of attorneys soon arrived at airports across the United States to provide assistance, and multiple individuals filed habeas corpus petitions seeking the release of people detained by CBP.
During the weekend of January 28-29, 2017, courts in California, Massachusetts, New York, Virginia, and Washington issued temporary restraining orders blocking the executive order from going into effect and ordering that CBP release individuals from detention.
Subsequently, numerous other lawsuits were filed challenging the travel ban. A complete and up-to-date list of cases, as well as case status information, can be found on the University of Michigan Civil Rights Litigation Clearinghouse website. On June 26, 2018, the Supreme Court upheld the travel ban, and reversed and remanded the 9th Circuit decision in Hawaii v. Trump. Since this decision, many of the travel ban lawsuits have been stayed.
