This is a cliche' but you theoretically you don't require a university to be successful. Steve Jobs, Bill Gates, and Mark Zuckerburg were all drop-outs but they're way on the top now.

From a more mature perspective it does for us Nepalis, even more so in the US. You don't only have things to look after graduation, but the period before that - the actual time you spend in a university. It's true that international students from better colleges get into good universities and/or with better financial awards at grad school.

 If you tell us the names of the universities specifically, we'd be in a better position to give a genuine feedback. If you're looking at those ranking, most of them are flawed, so you'd have to consider a lot of things before actually making decisions on universities.

I'd say go to a better university. You have some people to leave behind and  a job - that's just it. Remember that place was new when you came there the first time. It might have taken some effort to find the job. Try to find some people in a better university and plan about jobs and stuffs. With enough planning, this should be a no-brainer.
