Thank you again! I have to say, it is a bit ridiculous in my opinion that F1 students cannot fall back on their student status in case of AOS denial; I understand why it is so from a legal standpoint, in connection to the expectation of students to maintain nonimmigrant intent, but it seems a tiny bit unfair that it is such a huge risk. In essence, if a student wins the DV lottery (which has very low chances of happening), by applying for AOS they put themselves in an all-or-nothing situation: you either get a green card, or you lose your chance to keep studying in the US. It's a pretty brutal decision to have to make.
