What prompted this discussion was a conversation initiated by my wife with the senior Immigration Official. Unbeknown to me she had asked about Blue Books and Yellow Books and getting my name added to one or the other. He asked why after so many years did I need a Yellow Book? She told him something like to get him (me) to keep quiet because I always ask, every now and again, why don't I have my own Yellow Book. The long and the short of it is that she was told to go to the Town Hall and ask for a Yellow Book for me. They gave her a printed paper from Immigration verifying my personal details and address. If the Town Hall wanted a formal Letter of Residency she was to return to Immigration, with the written request from the Town Hall, and they would provide the same. Going to the Town Hall tomorrow so I will update when the Yellow Book is provided or otherwise.
