Nigerian and other foreign students in the United States have been advised to carry their immigration documents at all times as enforcement measures intensify across several cities.

The University of Pennsylvania, through its International Student and Scholar Services (ISSS), issued fresh guidance reminding students that they are “lawfully present in the United States” but must be prepared to show proof if approached by law enforcement.

The directive was contained in a February 18 email obtained by The Daily Pennsylvanian.

ISSS advised students moving around Philadelphia to carry photocopies of key documents, including an unexpired passport biographical page, visa page, I-20 and I-94 forms.

Those travelling outside the city were told to carry original documents instead.

For students on Optional Practical Training (OPT), the office recommended digital copies of their Employment Authorisation Document (EAD) card and OPT I-20, alongside a USCIS approval notice where applicable.

Permanent residents were also urged to keep copies of their green cards.

The advisory further instructed students to “remain calm, respectful and responsive” if stopped by officers and to memorise the contact number of Penn’s Division of Public Safety for urgent support.

It also warned against immigration-related scams demanding payment or sensitive personal information.

The development follows recent shifts in U.S. immigration policies, including expanded travel restrictions introduced in 2025.

In recent weeks, protests have erupted in parts of Philadelphia over federal immigration enforcement activities, with local lawmakers proposing measures to limit the role of federal agents in the city. (The Sun)
