I got an employment contract and an appointment at the German embassy. I went with all of the necessary documents and the embassy officer seemed satisfied with everything.
After a day, I received a call from the German consulate to show up in the embassy. I was not given any context of the invitation. So I came on time and then there was a kind of interview in which the officer told me that one of the agencies has raised some security objection to your visa application. He asked me whether I have visited Germany before or had any other business with German companies of some sort. I said no and it was the truth.
So I have never had any criminal record whatsoever in my country(not even a parking ticket). The officer said he does not know the details so he will call the Berlin office for more information and inform me later.
What can I do about this?
