Okay, then I read you reply wrong and have no idea what are you trying to say. The law I quoted is about inadmissibility, PERM is a process to create an exception for an inadmissible alien as described in the law. Recall that the exception is created via DOL certifying that there are no sufficient able, qualified, willing and available workers. PERM is a way to conduct this certification. Read my first message you have responded, it has the link to the law. I am also not sure what you mean by this "They do not do that at the administrative level (by denying PERM) " because the news item you are commenting under is exactly about the blanket PERM denial.
Yes, the present blanket ban is unlawful which will be overturned by the courts as arbitrary and capricious (similar to tariffs, 100k fee, and countless other things that this admin has done). I mean that historically PERM approval rates have been above 90%.
That's, like, your opinion, dude. For what it's worth, these bans are routine and had been issued many times before, none was declared "unlawful" by an actual court, nor it had been overturned. Usually what takes for the ban to be lifted is the company getting into compliance with the law and stopping the cute "nobody told us we should not ad in the Podunk Monthly Herald, we honestly thought this is the best place to source PMs!".
