F-1 visa and adjustment of status

[kimmie84]

hello
I already applied for an adjustment of status and I am gon get my finger prints done this fri..
I came here on F-1 visa and was a full time student until today
unfortunately I got dropped out of my one class so I am not a full time student no more
admissions office terminated my sevis and recommended to apply for reinstatement.
some people say I dont need to do that cuz I already applied for a green card. I am so confused
I also wanna know how long I do have until I apply for reinstatement status
thank u
