I think as long as you show an aptitude for the subject that you'll be studying, you won't have much to worry about. Honestly, 98% of universities are going to be lenient with international students because they want your money. Of course, they're never going to say that, but it's nevertheless true.
When I was in undergrad, I failed Calculus, had a D for Statistics, and I think a D in some Economics course which is why my GPA was so low (I think it might have been a 2.7). It was a mistake taking those courses, especially in one semester, but I hadn't decided on a major yet and they seemed like a good idea at the time. Obviously, I am terrible at those subjects.
Anyway, eventually my major was Art History, and I had somewhere between a 3.3 and a 3.5 GPA for those courses plus comparable marks for other stuff like History, Women's Studies, and German.
I got into the top department for research in my field despite the lower GPA. Even if there is a specific requirement, don't let it stop you from applying. You're not that far off from a 3.0 and they might say one thing and do another. Good luck!
