Poll: Will you apply for advance parole?

Granted that you are applying for the one of the three reasons:
1. Humanitarian Efforts
2. Studying Abroad
3. Employment Purposes

I would but it seems they value things in judging whether they should allowed back in like if you're married to a USC have USV siblings or USC kids. And I don't have any of those

Yes I want to go to Brazil.

Do you think I'll have a better chance of being let back in if I'm currently employed and taking a paid vacation?

I think the USCIS will take steps to assure that reentry will be highly likely.
I'm currently attending school here... do you think they would let me back in?

I have two USC daughters... Will they let me back in?

How old are you?

I'm 25

Per the preliminary changes the USCIS are trying to make for AP applicants under DACA, you would be able to get back in if your only problem was unlawful presence before getting DACA.

Once you get approved for AP under the 3 reasons listed on top of the page, re-entry shouldn't be a problem.

What about unlawful entry?

Shouldn't be a problem either. There might even be a possibility you can now adjust your status (in case you get married with a USC) once you're back in the US, since you're now entering the "normal" way.
