You can get a green card marrying a us citizen with DACA even if u entered without inspection....what u have to do is get married first here, then apply for advanced parole, go to ur country and when u come back u enter the country with inspection, then u apply for a green card...it works I've read in another forum that this girl left to Mexico and came with advanced parole and she is now gonna get her her green card ...I suggest u go and talk to an attorney first though.
