...which is why it's in the news, why it was leaked to some conservative site and got picked up by so many news sites.
It's a deliberate hook by NOEM's DHS, advantaged by clickbait journos and people who like to bandy this stuff about immigrants in everyone's face, to make people wary of migrants; and for tiny minds to believe this man either poses a threat to Americans or represents something that can be extrapolated by the fearful to represent the rest of the migrants they're pushing out of the country as similarly threatening.
Misrepresenting credentials is more widespread among Americans, including in this administration. It appears this man not only served the school districts he worked for, he did so with some degree of expertise that's not reflected in the reports of his misrepresentations.
Moreover, it's well known that a shortage of teachers and administrators has led MANY school systems to accomodate less experienced applicants, so I'm not sure to what degree his misrepresentations affected his ability to do the jobs or his performance. Certainly, at some point, he was an experienced administrator.
The immigration crimes appear to be administrative, mixed with questionable citation of his previous charges, like the drug charge in '96 that doesn't have the resolution listed, and the dissmissed one which DHS is now considering some kind of actionable threat.
And the gun possession. Bad, huh? 
I'll bet those gun possession charges are conveniently related to his immigration status. Neat.
