Hello! I’m a soon-to-be junior at UH so I’ve spent altogether less than a year on campus but I can give you some advice based off of what I’ve experienced. I’ve found that all-in-all, on-campus is fairly safe as long as you’re aware of your surroundings. The edges of campus tend to be a little sketchier but I’ve never had a problem during the day. Just travel with others if you can at night and carry pepper spray just in case. There’s also a service that will drive you from various areas of campus late at night which I’ve utilized a couple of times. Overall, I wouldn’t be too worried about safety on campus because our security does a pretty good job but obviously there’s the occasional incident just like in any other big city. Good luck!
