@Ponytail11, the problem is that you will not be able to get a visa if you cannot show proof of funding. It’s one thing to get admitted to a college, but that’s only part of the equation for you. You will not be able to get an I-20 from the school until you can show that you have the full amount for your first year of study, and you have to verify that you will be able to pay for the rest of the program. If you are able to satisfy the school, they will issue an I-20, but you still have to be able to show convincing evidence of financial ability to pay to the U.S. Embassy in order to get a student visa.
As others have pointed out, you are limited in terms of being able to work. On an F-1 visa, you can only work at your school - and for no more than 20 hours a week. Because your school is unlikely to offer you a 20 hour a week job before you even begin school, you will not be able to list potential earnings from work as a source of funding when you submit your proof of finances.
I worked with a lot of international students in a graduate program. We did not offer full funding, so those who needed full funding in order to attend school in the U.S. were unable to attend our school. Some of them were able to find fully funded programs & attend school in the U.S., but this was at the graduate level. I am not familiar with fully funded undergraduate opportunities. They may be out there; I just don’t know about them.
