During the past 7 years, I have been issued five UK visas (for 6 months and 2 years in length). I was recently refused because I wanted to travel with my mum. In my mother's passport and visa application is a different date of birth than what I have stated in my previous applications.
My mother is not literate and does not even remember when she was born. In processing her passport in my absence, officials determined her date of birth based on her narrative and events that happened in her early life.
What should I do, because I want to reapply?
