Thanks for your thorough comment mom. What you said sounds fair, but still a very strict interpretation on their side. I do have an alternative understanding of the situation. The Tier 1 at first mentioned that my request is to expedite a bio appointment and to be qualified for that I need to be adapting a USC child, be a member of US army, and few more that I don't remember. I then asked her to place a request for a Tier 2 call back then. At that point she changed her mind and said let's put the expedite request then. So I believe that they denied my request because my bio appointment is not scheduled yet. This is also supported by another forum member's experience, who stated that he placed an expedite request, the officer called back, denied the request as there were no bio appointments scheduled, but then that officer went ahead and scheduled the bio for him. But again, as you mentioned, he might have EAD and AP applications submitted as well.
At the end, if
@elisap decides to request an expedited processing and shares her experience, that would give us a better idea.
