As a lawyer specialized in immigration law, I represent you with the purpose of obtaining your visa or your spouse to spouse reunification in Germany.  You can engage me for the family reunification to your spouses, or children and other family members. I fight for the reunion to same-sex partners. I  represent you in visit visas and student visas. You need a blue card visa for Germany (relaxed regulation for immigration for high skilled specialists) - you need a business visa? I help you with your visa application at the German embassy. I file in cases against the German embassy to the Berlin Administrative Court and the Supreme Administrative Court in Berlin.
  

Legal proceedings against the German Embassy - as represented by the Foreign Office - always lead to the Administrative Court of Berlin. So you need a lawyer in Berlin.  After consultation, I can perceive files for your lawyer from another city of Germany in Berlin.
