Yes, his 10 year green card. He hasn’t received any extension letter. The only thing he received was his notice of action I797C saying they are continuing to process his application, but that the notice isn’t an approval of his pending application, petition or request. He has been in Mexico since May of this year. Should he have received an extension letter after the 797 notice of action? He wants to know if he can cross the border with just this notice of action letter.
