Maybe you can try to place a service enquiry. I did it in late May and receive the reply on June 1. Not sure if it helped but it never hurt to try.
Yeh I have tried two inquiries with NSC since my transfer. Both no reply after 45 days.
My attorney also sent in two inquiries. First expired after 45 days and no reply. Second has been two weeks and still no reply.
My congressonperson's office is also following up with them. No effect.
I think NSC is just not nearly as responsive or speedy as CSC.
My case status still shows that my case is pending with CSC, does it mean that it will be transfered to NE in the future or CSC will continue to process?
