Pinpoint,
Its good that you figured out everything. The jobs on campus and out of campus totally  depends on you and the situation in the school. If you talk with your friends in the school, they would tell you the things close to fact. If you have some money and your parents can back you up when needed then it will be ok for you.
I came here as a grad student and it was ok for me due to assistantship. If anybody in Nepal wishes to come to US then I would suggest him to come at Masters or PhD level. I have seen undergrads who are struggling and not able to complete studies. Its really costly and hard for undergrad student unless they have scholarships and are really determined.
Nevertheless, there are undergrad students who also have excelled both economically and in study too.

Good luck ahead.
