Don't get it twisted, he smuggled the extra-species members into the country. The only reason the tests he's performing are not illegal is because the laws haven't been written yet. He's operating without government oversight. He's not doing it out of the goodness of his heart, he's doing it for money.
It's not a "foreign exchange trip," you'd be smuggled across the border in the back of a trailer, thrown into a laboratory, and told, "Hey, let us collect your pee to pay off your debt to us or we'll report you to the authorities. And good luck getting a job anywhere else, the populace in these parts aren't comfortable with your people."
He wouldn't be offering all of the "spa services" if he wasn't trying to compensate for that.
And of course I'd still be pissed if the perpetrator was a big tiddy alien onee-san. Being the mastermind behind abductions and/or rape is even more heinous than the acts being perpetrated randomly.
