Strangely enough I have not worried about this until now. Both my daughters were born at RAFH Wegberg in 1981 and 1982 and both births were registered at the British Consolate in person by myself. Both children have British passports.
My youngest daughter now 35 has recently applied for an Open University course grant and because she was born in Germany has been asked to provide proof of where she has resided since she was born. Today I have typed out all the married quarter addresses where we lived and it took more than one page but most of them were in Germany.
What is is going on, the people in power seem not to understand the system. Maybe they don’t realise we used to have the Royal Air Force that actually served in overseas postings.
