Research fellowship in Germany

Fellow Awebbers

This is not my field at all but i have been asked by a colleague for an opinion. His daughter will be in receipt of a Post doctoral fellowship stipend, paid into a German Bank a/c, for research work carried out in Germany and she will stay in Germany for the entirety of the project (24 months). Seems that there is no liability to German tax or social insurances and we are OK with that. Anything to watch out for on the UK side though. I can't think of anything but a second, third or even fourth opinion from more expert people wouldn't be a bad thing.

Thanks
