Why not do it in his country of nationality and residence it seems you only want to come here to work imo. You can work and study for sure, but the hours are not full time. So many people want to come here to study/work, the country is overfilled with people here ilegally who have said they want to do what you are asking ... and overstay their visa and never leave ... and then live off my taxes.
Do it in his country, just my honest opinion.
