If i'm under daca and I use advance parole can my sibling ask to adjust my status ?

You have an unfortunate situation that many attorneys are uncomfortable with answering unless they have enough time.  It seems like you assume that you will get advanced parole.  The Trump Administration was not issuing advanced parole.  This policy may continue even when Biden becomes President. As a result, I strongly recommend an appointment or teleconference with a competent and experienced immigration attorney, who can take enough time to explain the situation to your satisfaction.  However, most will place a value on providing this sort of legal advice. The above is general information, not legal advice, and does not create an attorney client relationship.
