Visa date has expired but I-94 departure date still has a year remaining. Will the passport holder become undocumented and out of status? Will they face being barred from the U.S.A. for three or ten years depending on length of "Overstay" in terms of the visa if they leave before the date stipulated by I-94 departure date? Holder is an H-4 holder but turned 21. I-94 was officially issued and no -one from U.S.C.I.S. has challenged or contacted the recipient about the discrepancy. If said person attempts to leave before the I-94 and is barred, can said person challenge the bar given that person is leaving before stipulated time? Would this affect family members who are in status and are attempting to apply for Permanent Residence?
