MY College Doesn't Offer my Major!?!?

<p>I am going to UMASS Lowell. I didn't get a high GPA in high school and time was running out for the May 1st deadline and all at the same time I was trying to figure out what to do with my life. So now I'm stuck at UMASS Lowell, studying Sociology. BUT I want to do International Relations and they don't offer that!? They do offer though, political science, peace conflict studies major and I figured I'd minor in Arabic Studies (including learning the language). So if I took courses somehow related to International Relations, as undeclared and then I transferred out in my first or second year would I have problems majoring in International relations? I also plan on perusing for a masters degree.</p>
