If you’re a senior graduating this fall or in the spring, make sure to stop by the advising office of your particular school to make sure everything is in order.  Before going to the Harpur Academic Advising, in Academic B, you should stop by your major department to make sure everything shows up correctly on your DARs; if not, they can request exceptions. 
If you studied abroad, make sure you’ve turned in all appropriate forms to the Office of International Programs and to Harpur Academic Advising.  In HAA, processing can take up to two weeks, which could be enough to keep you from registering on time or even from graduating on time. 
I was there last week and right now is definitely the busiest time to visit HAA, but you should do it anyway. It’s a fail safe for your graduation date.  They have walk-in hours Monday through Thursday 10-12 and 1:30-3:30. Take advantage of the resources before you so you’re not haunted by unfulfilled requirements.
Even if you’re not graduating right now, it’s still a great idea to visit HAA and make sure everything is in order.
