It seems that you didn't read the article. I'll help you with the fraud part:

> When I was at USCIS," explained Law, "you would have registrations or petitions with very common names. The belief from some of the fraud folks was that some of the common names were inserted in there and then these businesses, after they won the lottery, would then go out and actually find somebody [with that name] as opposed to having a real candidate in place."

> One form of H-1B fraud involves companies colluding to file multiple petitions on behalf of the same foreign worker. This serves to give the IT consultancies involved in trying to bring this worker to the US a greater chance of having their applicant selected, and of collecting a commission. As above, that's supposed to be more difficult under the new system.
