This question already has an answer here:
When I was 17, I applied for a UK visa with my friend who was noted as my company (since she’s older than 18). On my visa, it specifically says that I can only enter the UK if I am accompanied by her. Now I have turned 18 and would like to travel to the UK alone. Would it be allowed for me to travel without my former company even though it says her name on the visa? Or would I have to wait till my visa runs out and apply for a new one?
