Hi there, my doctor who know me more than 6 years had left the surgery. I would like to have 2 referees with none of them from a professional body.It is possible or not ???. I am applying for the british citizenship.  Please advise I need some help

You need to find two people who kow you personally, like a teacher, doctor and there are many other people who are included in this categoy.  Read Guidance notes carefully and follow the instruction on it.

Good Luck
