UND Application Change Question

I submitted my application in early August. At the time I was working about 20 hours a week at a BBQ restaurant and it says so on my application.
Shortly after I submitted my application, I was offered an internship for my congressman and quit my job for it.
Should I contact UND and let them know this? I think it could really help but don’t want to be a nuisance to the admissions office.

Yes, let them know.

Absolutely, tell them!
