Parole in place. Basically you get to clear an EWI without having to leave US.

Only really helps if you marry a citizen (or make one and wait 21 years) since in those cases status violations and unlawful presence aren't a factor but you still must've been admitted or paroled into the US to adjust.

Also it's not just for DACA, it's for anyone who's been in US for 10+ years but that's every single DACAer.
