Well it depends. ARE you able to adjust your status? ie. were you just a visa overstay or do you have an EWI that you need to clear? If it's a routine case and you already have DACA and don't have to worry about getting deported if you come forward, you can do it yourself and it's routine.

If you have to clear an EWI then while technically possible that you can do it yourself, much as I can technically give myself a tooth filing, I wouldn't recommend it.
