He says he is a British Citizen which implies a British passport. The main issue will be residency. I believe the issue is the difficulty of conducting security screening. Previous advice has been to attend a British university and gain residency that way; it would appear to limit visits home to 28 days per year.
You might risk extra home visits on the assumption that the UK Border Agency dont share information with other Government Agencies and Ministries.
At 18 you have plenty of time for a degree course and still join at age 22-23. The only bar would be fees of up to £9000pa with food, accommodation etc on top of that.
