<p>Daniel, I am an international student turned permanent resident myself as well. I was in the same boat except I was over 24 when I gained residency, so I do not know how the rules will apply to your particular case, but I have no hostility toward you.
As many people mentioned already you probably cannot file as independent. And if you file as dependent and your parents show no or little income there surely will be questions due to the fact that you need to show substantial income to be accepted to US college and get the student visa. Besides this forum, financial aid adviser at you college might be a good person to ask.</p>
