Federal Republic of Nigeria
The Nigeria Immigration Service, under the Federal Ministry of Interior, administers expatriate entry and residence, the core document being the Combined Expatriate Residence Permit and Aliens Card (CERPAC). Nigeria is unusual in operating an official agent-certification scheme, the Nigeria Certified Immigration Agent (NCIA). Headline routes include the STR employment route, CERPAC, the company Expatriate Quota, the Investor Visa and a Permanent Residence permit.

Republic of Sierra Leone
Sierra Leone publishes official immigration service links through the Sierra Leone Immigration Department, online entry visa filing through evisa.sl, and work and residence permit filing through the Unified Permit portal. The current Visa Atlas packet covers eVisa, residence permit, work permit, student residence, investor residence, and extension/re-entry handling. The Ministry of Labour website had an expired certificate during review, so work-permit coverage relies on the official Unified Permit portal and Immigration Department references rather than that host.
