save your energy for graduate school. America will still be here in 4 years. I promise it will. UG is very expensive. What makes you think your school will waive your tuition? UG students almost always pay their full tuition. If you graduate with an undergrad degree it will be VERY hard to find a job because they don't give H1-b visa's to those with only a bachelor's degree. So you will need to go to graduate school anyway. In graduate school you can get assistantships fairly easily which will waive your tuition. The assistantship will give you good experience for your resume. It is much easier to get an employer to sponser you if you have a graduate degree because of immigration regulations. You will more easily find your way to a green card and a real future in America. As an undergrad you will transfer schools every other semester trying to find a better deal, drop out to work under the table in Ocean City, drown in credit card debt and be too ashamed to call home lest your mother find out that you are not going anywhere. I have seen too many undergrad Nepali's get lost here. In my opinion you are too young and immature to handle it. But when I was 19 I thought I was pretty mature so I am sure you will not be convinced that you are really still just a child.
