Pretty much what OSHA said is the "usual" or what everyone knows or will respond. Unfortunately 821D petitions aren't included in the processing times in the uscis website because they have a whole mess going on now in their offices with new and old petitions and even those who sent a request. Has Anybody sent their petition on or after October to the california service center and still waiting??
They should really enforce the 3month period for deferred action as well so u know where you are standing at. I sent mine onseptember 21 sent RFE on nov 13 and still waiting..Definitely sucks
