Situations we have successfully resolved.
A foreign national was dismissed by their employer. Their residence permit was tied to that employment — deportation proceedings were imminent.
Residence permit successfully extended. Obligation to leave the country averted.
A client's existing residence permit needed to be converted to an EU Blue Card, but special personal circumstances made a standard application impossible.
EU Blue Card successfully obtained, taking all circumstances into account.
A self-employed freelancer needed to secure their own residence permit and bring their family to Germany — while managing the uncertainty of self-employment income.
Residence permit secured for the freelancer and family members.
A client abroad faced complications with their visa application at the German embassy. Communication had broken down and the process stalled.
Mediation between client and German embassy resolved — visa process resumed.
