Advance Parole

Hello guys, I am in a decision to leave or not to leave the country with AP, (DACA) since I was detained by the border when I was 15 years old it was only once I do not remember exactly what happened but I do not know if I have voluntary deportation since I believe Remember that maybe they took the fingerprint of one of my hands but they did not take a photo and I do not remember if they signed something and they never told me that I had a punishment not to enter the country, my sister who was 13 years old was with me, they let us out in a few hours and she Is already a citizen and never appeared anything ... my question is if someone from you has been through something similar? My lawyers say that they do not believe that it is a serious offense since it was a minor, but if someone has been through the same situation I would be very grateful for any information !!
