Washington has enforced one of the most sweeping immigration restrictions in modern American history, and the effects are rippling across the globe. As of January 1, 2026, Presidential Proclamation 10998 fully or partially suspended visa issuance and entry for nationals of 39 countries, building on earlier restrictions that already covered 19 nations. The move has upended immigration plans for millions of people and reshaped how countries think about diplomatic relations with the United States.
Countries facing full suspension of all nonimmigrant and immigrant visa categories include Afghanistan, Burma, Burkina Faso, Chad, Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Laos, Libya, Mali, Niger, Sierra Leone, Somalia, South Sudan, Sudan, Syria, and Yemen. The list also extends partial suspensions to a wider group, and the State Department separately paused immigrant visa processing from 75 countries whose migrants it determined take welfare from American taxpayers at what it calls “unacceptable rates.”
The White House reports that since Trump returned to office in January 2025, more than 605,000 people have been formally deported, with an additional 1.9 million self-deporting. The administration claims a total of over 2.5 million undocumented individuals have left the country, though independent researchers at the Center for Migration Studies dispute those figures significantly. The Brookings Institution reported in January 2026 that the United States experienced negative net migration in 2025 for the first time in at least 50 years.
For Nigerians, the impact is direct. Presidential Proclamation 10949, which preceded the current restrictions, specifically included Nigeria among affected nations. Many Nigerian applicants who had been in the process of applying for immigrant visas have seen their cases stall. Family reunification pathways that once existed have been cut off. The State Department has stated that immigrant visa applicants from affected countries may still submit applications and attend interviews, but actual issuance remains suspended.
The administration also introduced a new rule ordering diplomatic missions worldwide to ask nonimmigrant visa applicants whether they fear returning to their home country. Applicants who answer yes face automatic refusal of their US visa applications, effectively blocking a traditional pathway through which people later sought asylum after entering on tourist or student visas. Legal experts say this move fundamentally reshapes how the US processes protection claims.
The Department of Homeland Security conducted over 206 million benefits eligibility checks in 2025, cross-referencing immigration status with welfare usage, health insurance claims, and even car insurance records. Civil liberties groups and 20 state attorneys general have filed lawsuits alleging these practices violate the Privacy Act of 1974, and courts are actively weighing the legality of several components of the administration’s immigration architecture.

Courts have not been entirely accommodating to the administration’s ambitions. On April 24, 2026, the US Court of Appeals for the District of Columbia upheld a lower court ruling blocking one of Trump’s key immigration proclamations. Judge Michelle Childs, writing the majority opinion, stated that existing immigration law does not allow the president to remove individuals under summary removal procedures of his own making.
For global businesses, universities, and governments, the visa crackdown is forcing difficult decisions. Indian tech professionals, African scholars, Latin American students, and Middle Eastern businesspeople are rethinking their American plans. The ripple effects extend to US institutions that depend on foreign talent and tuition. The economic consequences of the restriction, beyond the humanitarian dimensions, may become more visible in the months ahead as innovation, enrollment, and trade data reflect the new immigration reality.
