The US Department of Homeland Security (DHS) announces visa rule changes that will place fixed time limits on visas for certain non-immigrant categories starting September 2026. Multiple reports say the change applies to international students, exchange visitors and foreign journalists, including Nigerians. According to the outlets, the new policy is introduced through a DHS government notice dated July 16, which outlines how long these visa holders can remain under the visa category and how extensions will work going forward. The reports also describe the announcement as part of a wider US approach to immigration and border policy, though the articles focus primarily on the visa framework rather than specific political goals. While the coverage varies slightly in wording, they consistently state that DHS is moving toward set time periods for the listed categories and that the implementation date is September 2026. The sources do not provide further details beyond the existence of the fixed time limits, the affected visa types, and the start date.
