If I am reading the post correctly, you have been working as a freelance designer for two years since graduating secondary school. I agree with other posters that there isn’t anything in your profile that would stand out for admission to a selective liberal arts college, and you’d have an extremely low chance of getting any financial support.
It is unclear what you hope to gain from Vassar, unless you are simply looking for an expensive, cozy place to spend time. It sounds like you are more into art design and web design. With those skills you should be able to pick up more work and academic training closer to home at less expense. Since you did not choose the college path before, it would be better for you to complete an academic certification where you are. Then you can apply to US and other schools based on the merits of your artistic talent for a graduate program (at a university, not a college). For a PhD program, you may even get funding.
