"A Nigerian national would like to visit Germany and has applied for a Schengen visa. He was refused without reasons and would like to appeal against the decision.
He was informed that national rules apply in this case, and that he should independent legal advice in order to challenge the decision of the German authorities."


You cannot appeal against a decision to turn down an application for a visa. You can however re-apply or request that the original application be reconsidered. In that case you write in and request a review of the decision. You send the letter to the body that took the original decision (the embassy, the consulate or the Migration Board).

Remember! According to the Schengen regulations you must have a medical insurance.
