You can also buy guns at walmart in 5 minutes.Sorry 10 minutes, just show an ID.Any ID!
It takes less time to get guns and kill people than going through a TSA clearance.
Not here in Arizona, and I think most of the other states have similar rules. You must be a
legal permanent resident (green card holder), or
US citizen to buy a firearm. I know, because I'm neither of these, and I tried. If someone is here on a student visa (which is the subject we're dealing with) the above is true, so any ID or not, you aint getting a shooter. The best I could do was get a nice high-powered air rifle for when I go camping. There are parts of downtown Phoenix you could probably get a gun illegally on the black (or latino/hispanic - sorry, had to say it!) market, but the statement about Wal-Mart seems like something you concocted.
Most of the schools would like their stundets {sic} to live {sic} the country once their training is done, unless they remain with them as instructor. (remember, they are still responsible for you and if anything happen people will be going back to them)
Indeed, students are expected (and legally required) to leave the country on completion of their studies on the M-1 visa. They must be out within 30 days of finishing their training. If not, the student will be "out of status" (illegal), and there may also be serious repercussions for the flight school as they also have some responsibility to ensure students don't do anything untoward.
unless they remain with them as instructor
This is not allowed on the M-1 visa, but is on a J-1. The only option to remain with them as an instructor on an M-1 visa, would be if you were eligible for OPT (Optional Practical Training) which would be unpaid and not really worth the hassle, as it's a pain in the ass to set up, and you are only allowed something like 1 month of "work", for every 3 months of your completed study.
Hope this helps, and if I am incorrect in any way, shape or form, please feel free to correct me. Thanks.
