I am a green card holder, want to file my son F2B. He is international student USA (India Citizen, 22 Age, un-married. How long it would take his GC?

Currently, the July visa bulletin “dates for filing” chart shows that there is visa availability for those who submitted petitions before 9/22/16 under the F-2B category for unmarried sons and daughters over the age of 21, and the “final action dates” chart shows availability for petitions filed before 9/15/15. So it will likely take approximately five years before an adjustment of status application can be filed as long as USCIS accepts the “dates for filing” chart when your son’s priority date becomes available. (That is assuming that visa chart progression remains approximately the same). On the question of OPT, in our experience, we have not seen students denied OPT by USCIS where they have had immigrant visa petitions pending or approved.
