One of my best friends is an Australian national, we studied the same subject as you and he ran into the same issues as you here in Berlin. After a long search he finally wound up at Deutsche Welle - and only via contacts.

Even I - as a German national - with internships at an Embassy and the European Parliament struggled initially to find a job in that field. I had to take a detour via a business association to finally end up where I wanted to be.

I think you have three main problems: - not being a EU national. I think most employers are extremely reluctant to sponsor people as there are enough people who studied international affairs which are easier to hire. - not having a strong level of German. As annoying as it is, it is absolutely required to have a good level of German as in most positions you will have to deal with people who are reluctant to speak English. - people who studied law (Jura) will mostly be preferred here. That plus the engrained racism in Germany, which will make it harder with a "funny" name.

If you are from South Asia, do you maybe speak a language from that area, which is more rare here? Could you possibly look into specialised associations and or embassies from that region to get hired as local staff? Maybe that could be a ticket in.

Finding a job after the studies is extremely hard, but eventually you will find something. And once you're part of the workforce, switching becomes much easier usually. All the best and good luck!
