None of us here are practicing attorneys. You should consult a lawyer or go to an information session to learn more about DACA. Chances are that if you cant determine eligibility based on the rules on the official uscis webpage, then you need to speak to someone who can help you with the filing process.

Think of us as those who can help you answer minor questions about what to put on a section of the application, what new information came out regarding daca/cir. People can mislead you on here, so play it safe. If you need to learn more about what people submitted for proof, there are official threads on here for it.

Were you 15 when you came back to the US? Strict interpretation of the rules show that you must have entered BEFORE 16, so 15 and under. Do you have a high school transcript that covers the year you turned 16? Anyways, my advice is speak to an immigration attorney.
