My name is samuel and I want to get invitation to visit Belgium.and also iwant to know countries that ghanaian citizen does not need visa to enter to that country in the world.

Belgium, just like all 27 members of EU operates on Schengen agreement. You will need a resident of European Union (any country ) to invite you and to sponsor you. You will receive Shengen Visa for specific period. If you don't leave Europe on time your sponsor will face $25,000 fine.
