It has been pending more than 3 mothes in TX center. I called the coustmer service and the guy told me that TX is processing Jan 1st cases now. I need to wait for another 3 monthes. Can I request service at our local office
-Just try, and not hurt you.
or should I have to lie that I have an emergency to get the service request at our local office?
-You need to provide the emergency evidences. You can apply for the h1 visa to come back if you do not have AP in hand.
another question is that I have a valid H1 visa but I don't have EAD. I heard that if I use AP, when I come back to USA, they will ask my EAD because AP is always associated with EAD. is that true?
-Not true. You can just work for your current employer without EAD after you use AP to come back though your status will not be H1 in this case.
Can I just use AP without EAD?
-Yes.
