a PhD programme in the UK? or where?
where have you been living for the last three years?
in the UK, if you have EU citizenship and have been living in the UK for three years before you start your PhD, you can get full funding from the research councils. if you have EU citizenship, even if it is British, but haven't been living in the UK for the last three years, you can get "fees only" funding from the research councils.
check German sources, and contact the university where you will be going.
