Hi I am a UK Citizen living in Turkey with my Turkish Husband. I have Turkish Kimlik ( Identity). My husband has a valid 10 UK visit visa. My eldest son ( UK Citizen) is stationed in Germany for 3 years, he is an engineer with the British Army. We want to visit him in Germany for 3 months this winter, do we need to apply for a Schengen visa for my Turkish husband or can I just take him with me exercising his right as a family member of an EU Citizen?
