Steps after Canada study permit refusal from Nigeria: (1) Read the refusal letter carefully — IRCC gives specific reasons; (2) Common reasons: insufficient financial proof, weak Nigeria ties, unconvincing study plan; (3) You can reapply immediately — no waiting period; (4) Address each specific refusal reason in your new application; (5) Improve your study plan — be specific about why this institution, programme, and why Canada; (6) Show stronger financial proof — a co-applicant parent who is a business owner or salaried employee helps; (7) Consider institutions in smaller cities — Halifax, Regina, Saskatoon — which may have lower refusal rates for Nigerian applicants.
