Re: Good for Trump
I'm not suggesting the government website is how things really work. I'm merely pointing out there are the rules to prevent these visas from being mis-used in the manner described by Trump. 'Fixing' this by changing the law won't prevent companies already breaking the rules from breaking the rules. As I said, laws are useless without enforcement.
Your friend is entitled to be paid at the higher rate of either the prevailing wage for people doing the same job in the same area (regardless of qualification), or of the wage people of comparable skills and qualifications in the same company employed for the same reason.
Note that this isn't about how much a qualification is worth, it is about whether a qualification is recognised (you are either qualified or not qualified). If the job spec requires a qualification, then the company absolutely recognises that your friends qualifications are comparable to the qualifications of others doing the same role and therefore they are breaking the law by not paying your friend as per the rules outlined for the H-1B visa. The only way I can think of around this is to not require a qualification in the job spec and to officially not recognise qualifications from countries other than the US (though they could still land in hot water, as the US government may formally recognise qualifications that your friend holds).
