I (U.S Citizen) have already filed green card petition (I-130) and adjustment of status (I-485) for my parents who are here on visitor visa 3 months ago. They already got receipt notice with A# for I-485 and their case is still pending.
I-94 for them is expiring in a month. Do they need to renew it ? Will there be problem during Green card interview if their I-94 expires ? What if their Green card gets denied, will they be questioned on overstaying when re-visiting ?
