The Department of Homeland Security announced on December 2, 2025, a new immigration ban affecting nationals of 19 countries, marking one of the most sweeping entry restrictions introduced in recent years. The policy, detailed in internal memorandum PM-602-0192, directs consular posts and border officers to suspend the issuance of most new visas and to limit entry for individuals from the listed countries, with narrow exemptions for specific categories of travelers.
According to the directive, the restrictions apply to nationals of Afghanistan, Myanmar, Burundi, Chad, the Republic of the Congo, Cuba, Equatorial Guinea, Eritrea, Haiti, Iran, Laos, Libya, Sierra Leone, Somalia, Sudan, Togo, Turkmenistan, Venezuela, and Yemen. DHS stated that these countries were identified following an interagency review that found significant deficiencies in identity-management systems, security cooperation, and information-sharing practices. The suspension is described as temporary but will remain in effect until each country meets the required security benchmarks.
The memo clarifies that several groups will continue to be eligible for visas or entry despite the new restrictions. Diplomats and individuals traveling under international agreements will not be subject to the ban. The policy also permits limited humanitarian exceptions, including emergency medical travel, threats to personal safety, and certain cases involving minors or vulnerable individuals. Applicants who can demonstrate a compelling national interest, such as supporting critical U.S. government operations or providing essential expertise, may also qualify for case-by-case waivers. These exceptions, however, require high levels of documentation and are expected to be applied sparingly.
For most applicants, the policy is likely to bring widespread appointment cancellations, visa refusals, and extended delays, even where USCIS has already approved the underlying petition. Immigration advocates and legal scholars note that the structure of the ban closely parallels earlier country-based restrictions that resulted in prolonged litigation. They also point out that the memo does not publicly explain how the 19 countries were selected, a factor that may invite legal challenges if the criteria remain undisclosed.
The memo provides no definitive timeline for lifting the restrictions. DHS intends to conduct periodic reviews to determine whether countries have addressed the deficiencies cited in the interagency assessment. Until then, consular operations for nationals of the affected countries will remain significantly constrained, and only a limited number of applicants will be able to qualify for exemptions or discretionary waivers.
Observers warn that the policy could have far-reaching consequences across the immigration system, including prolonged family separations, uncertainty for workers who depend on routine visa renewals, and logistical difficulties for individuals residing in third countries who hold passports from one of the designated nations. Members of Congress have already called for greater transparency regarding the selection process, waiver guidelines, and review timelines.
For now, the December 2 memo stands as a major shift in U.S. immigration policy, and its full impact will become clearer as implementation continues across consulates and ports of entry.
