I have heard stories (that don't seem too uncommon) of unscrupulous companies doing a variety of things - including charging the hopeful visa recipient payments to secure a job, paying the required salary only for the months leading up to the H1B interview and then lowering the salary immediately after, etc. Not sure what fraud these new rules will prevent, if they are implemented.
