I'm a Greek PhD student living and studying in London. In one year from now I am required to do a "secondment" in a certain university in Germany which has a six-month duration. Having a Greek passport means that I'm a EU/EEA citizen. My girlfriend is also Greek with a Greek passport. We are not married.
My question is the following: Can I bring my girlfriend to Germany for the 6-month duration of my secondment without any restrictions? Will she be allowed to stay for this long, without having a job, just being my partner?
