If you were a minor and in the U.S. you would have been a derivative....obviously that is not your situation.
As an adult son or daughter of an LPR, you must be unmarried to be petitioned by LPR parent(s). IF so, you will not be able to file to adjust status unless in a lawful non-immigrant status. Even if they naturalize, you would still be a preference category alien relative. IF you have unlawful presence, you will trigger a bar to re-entry for 3 or 10 years when you depart. Depending on where you are from, your preference visa (F2B) may not be "current" for a long time, enough time to overcome the re-entry bar.
However, IF you have filed a frivolous asylum claim and it is deemed to be frivolous by the IJ, you would be banned from any and all benefits under U.S. immigration law for life.
IF you have a realistic asylum claim, stick with it.
