after a quick entry into Google for "fashion model visas" I found this website. there is allowances for granting a "work" visa up to three years provided that the conditions listed are met.
one of the conditions is for models of "distinguished merit and ability". I would say that some of the models on Pacino's website qualify, however, I am not the one making the visa decision. The person evaluating your application for this visa will no doubt be a 300 pound butch dyke. but good luck.
