When they got the H4 status, they should have got the H4 I-94 (with the H4 approval notice), right? That H4 I-94 has overriden the F2 I-94"
Thanks.
I never ahd H-1 I-94 and my wife also never had H4 I-94, is it a problem??
-The H1 or H4 I-94 is part of the approval notice (in the same page). The H1 I-94 is in the right lower part of the notice. You may contact your HR to get the H1 approval notice and detach the I-94 and keep it. Your spouse's H4 I-94 should be in the left lower part of her H4 approval notice, so check the notice and you will find it.
See the following website for the H1/H4 approval notice and the attached I-94:

we change several times of H-1 and H-4, no I-94 updated,
is it a big problem to return back to USA
