Sunday Goshit, a University of Iowa adjunct assistant professor and Nigerian immigrant who arrived in the U.S. in 2000, was approved for naturalization in October 2025 after passing his citizenship interview. His naturalization ceremony scheduled for January 16, 2026 was canceled without explanation less than a month before the date. Goshit and his wife filed a lawsuit against U.S. Citizenship and Immigration Services in federal court challenging the halting of their naturalization application.
