Advance Parole

Disclaimer: My question might be a question that has been answered already but with the current political climate I think everyone is making different decisions and I want to gauge how people would view my situation.

I am currently a graduate student and applied to study abroad in Rome through my school. I got accepted but I am hesitant to fully commit. I am a DACA recipient, and have been in the US since I was 9, I have a clean record, a college degree and two years of grad school under my belt. I asked my family what they think and they do not seem to be supportive at all of me wanting to travel to Rome to study (I love history and architecture, Rome is the perfect program for me). I understand why, it is risky and I might never see them again if I can't come back in, but has that happened in the past? Have people been denied entry?

There are three main things I’m considering right now:
1. Besides the Advance Parole that I would need to apply for (which, if I need to leave by end of September, I'm assuming I will have to submit my application in the next two weeks), I would need to renew my DACA before I leave since my DACA expires a week after I'm supposed to come back to the US. This means I have to time everything right and hope there are no hold ups in my applications so that I can get my fingerprints taken before I leave the country.

2. My program is two and half months long, I know other DACA, advance parole recipients only leave for two or three weeks at a time, with the unstable policies in place two and half months seem like a long time. This means more time for the current administration to make changes while I am away.

3. If I am waiting for advance parole, should I buy my tickets last minute if I decide on going? Or should I buy them now while they are cheap?

This process is super expensive and the program itself is expensive. I would deplete my life savings but this is something I have been dreaming of. At the same time I am conflicted. I am pretty much deporting myself by leaving this country that I love. It is scary to think I might never see my family or friends again. Plus my parents are not supporting me, I understand why, but this is the first time they have fully refused to support me.

If my advance parole document is denied once I try to come back, is that the end of the road for me? Should I have attorneys ready just in case that happens? Can they do anything? What is your input on my situation? Should I go on this program? Also what has been the recent timeline for advance parole and daca renewals? I keep going back and forth on what I'm going to do and any insight would help.

Sorry for the lengthiness...thank you for your time.
