I have filed extension of H4 for my family. The I94 validity is till Sept10, the package was delivered on Sept1 (Lewisville, Austin center). I already have my approved I797.
1> Is USCIS going to send me the receipt in post? How much time will it take?
2> Is it risky if I don’t get the receipt number by Sept10th? I basically any document to prove their legal stay here.
3> Can I call USCIS and enquire about the status?
