Part of the game is to define jobs in such a way, no one can fill them. Then lo and behold, a guest worker shows up with all the exotic requirements on their resume. How convenient /sarc. This way the employers can pretend they are not replacing American with CHEAP guest workers who are virtual indentured workers.
This article is just cheer leading for more guest workers. We currently do not create enough new STEM, including IT, jobs for new grads, much less experienced IT people.
Yet we continue to import an alphabet soup of guest workers. At last count we are down to 125,000 new legal workers each month. Those in IT, and I'm certain other STEM professions, also compete with illegals (visa overstays).
