He could be denied since, on the basis of the I-130, the consulate may believe that he is planning to immigrate. He would have to show proof that he still has ties to the UK and is not planning on staying longer that his visa allows. I suggest that you contact an experienced immigration attorney for a face-to-face consultation and give him/her all of the facts surrounding your situation. He/she would then be in a better position to analyze your case and advise you of your options.
