just last month our family visa was approved. my husbands visa was only foreman they approved it because we have given them the company's contract stating that he's design civil engr and a copy of my husband's credentials like diploma, transcript of records (they asked for those papers to make sure that he really had finished a degree not just a 2yr course)
but try more until you get your family visa. or better yet ask your wife to look for a job here.
