What is the difference between Ghana custom service and Ghana immigration service?

The Ghana Customs Service is primarily responsible for regulating and facilitating international trade by managing the import and export of goods, collecting duties and taxes, and enforcing trade laws. In contrast, the Ghana Immigration Service focuses on managing the movement of people across borders, including the issuance of visas, residence permits, and ensuring compliance with immigration laws. While both agencies operate under the Ministry of Interior, their functions and areas of responsibility are distinct.
