Let's see. You worked illegally for six months. You knew you couldn't pay the cost of education in a four year college/university. So you lied to the people in the embassy just to get into US. If you had told them you would go transfer to a community college once you came to US, you wouldn't be here.

Most people have pointed out that it's very unlikely that you will get caught if you go back and return. I believe them, because the officer at the port of entry wouldn't have all this information. But I encourage you to go back. At least they have a better chance of deporting you than if you stay here.
