Ok, so imagine this: You're a professor in the United States on an O-1 visa. A visa which is about to expire.
With these facts in mind, what would your logical choice of actions be?
(a), File paperwork with USCIS to have your visa extended?
Or (b), cross the border into Canada, a sovereign and separate nation from the United States, and try to sneak through the system and get your visa renewed through the back door?
Let's say, for the moment, that you chose (b). If the United States were, for some reason, to deny your renewal, and you were to suddenly find yourself stranded in a foreign nation, what do you do then?
(1), Whine to the press about "discrimination" and "profiling?"
Or (2), Suck it up, move your family to Canada, and make a new life for yourself? (Heck, you could even elect to return to your home country, from which you came over on a TEMPORARY visa, if you so chose.)
My sympathy for assistant professor Mohammad Ramadan Hassan Salama, who chose the worst of all of the options, is running quite low.
For such a self-proclaimed "smart guy," he really seems to be quite a bonehead.
