You can definitely have a hand gun, or a small cannon, if that’s what you mean.  But you’ll need to check with your school about how they handle that.

OK, so a hand gun.  The short answer is, this is not something that most universities would allow, although there are exceptions.  For example, at MIT, students have the right to keep guns in their dorm rooms.  The idea here is to protect against people breaking into your dorm and stealing your stuff.  Students are not allowed to take guns into school buildings, because this is a violation of campus security.  Many colleges have also started making students pledge not to bring guns to campus, even if it’s allowed by your home country.  Your campus might also have rules about how you can get the gun there, like bringing it in your car.

Can I bring a gun to college?

Well, that’s a pretty complex issue!  It depends on your country, and on your college, and also what sort of gun you mean.  Are you talking about a hunting rifle, or a handgun, or a “small” cannon, or a small submarine, or something else?

A small gun, like a hand gun.
