I am currently in the US as a grad student. My sister is a US citizen.

Can she apply for my green card and adjustment of status? Would that make the wait time a little shorter than normal wait time of 10 years since I am already in the US?

OR will I become out of status from F1 and become illegal once I130 is applied?

From what I understand, I cannot leave the US while the application is pending. Would documents like advance parole help when I go home to see my parents?

Or it would just be better to wait till I finish school and apply for H1?

Please advise.
Sincerely.
