What are the requirements for being considered independent for financial aid for medical school? Is it enough to be independent for the last few years on tax forms?

I've also been looking at this, but for undergrad reasons (just starting undergrad at 25). This is what I found that seems official.

Hope this helps!

A person in professional school (medical school) is automatically independent.
