I agree, but if I were making the case to the INS I would phrase it differently: feeding someone who came to town specially isn't remunerating them, it's covering their expenses. And covering someone's expenses doesn't take money away from Americans who need jobs — because the American who didn't get the unpaid gig because this foreigner got it instead, is now sitting at home and consequently doesn't have travel expenses that need covering.
