Regarding international universities there are only a few recognizable names like Oxford, Sorbonne etc. UBA is definitely not one of them. So, hardly you will be able to impress somebody with your UBA degree.
On the other hand, it is better to graduate abroad, than from some low rated university in the States. Just because there is no direct comparison. Some of my friends got Ph.D. in Biology from Moscow University and some in U of Illinois in Chicago. So, several times I've heard an opinion that it is better to get a degree from Moscow. This way you are considered to be an "international scientist" that is basically is a category of its own, while, UIC is just a university #83 in the ranking.
So, I'd say if you would be able to get a scholarship from top ten universities in this list - up to John Hopkins, then definitely go for it.
U of Minnesota vs UBA - Frankly, I don't see much difference. You just need to decide on what is better for you on other criteria. Basically, it comes down to
If you want to see the world and get an international experience - go to Minnesota.
If it is important for you to stay with your friends and relatives, stay here. That's about it.
7 years here vs 4 years in the States. What is your motivation? Do you want to get enrolled into PhD program in the USA as soon as possible? I think it is a legalized form of slavery. You work for free for your boss. You are supposed to spend all your time in the lab. It is up to him when you will get your degree and before that you can not do anything. If you get a Ph.D in 5 years, you are lucky. In some places 10 years is considered to be a norm. And after that you are out in the world on a shitty postdoc salary, because finding a job outside of academy right away for a foreigner is near to impossible. Or do you have a different plan?
