I have applied for the visa appointment from German embassy in Tehran for my parents. After a very long waiting time (almost 5 month) they went for their appointment in mid September and I have prepared their required documents exactly according to all guides and provided information in the website of German embassy. Unfortunately the staff of the embassy at the interview counter had the most terrible and rude treatment with my parents with the excuse that they have too many documents with them! He was shouting at my parents (60 years old ) and shooting the documents at them with the worse possible manner. Unfortunately the German embassy is one of the worse European embassies in Tehran which there are many cases of rude and ill-treatment of visa applicants by the staff. The sad thing is that these are the Iranian staff working there which have such behaviors with other Iranian citizens!
