Hi whereisavalon,
What was the reason given for refusal?
I guess that a visitor visa was applied for?
Did your friend fully comply with all the required documentations? including a letter from his employer?
Take a look at the UK Border Agency website to review all needed requirements.
Then search this forum.
You will then be better able to ask some specific questions. There's a lot of experienced and helpful people here who will be pleased to help.
