想给议员写信要求关注relink I-485的case，求好心人给模板

I filed NIW I-140 & I-485 on 07/07 to NSC. 06/07 I-140 approval.I filed EB1-B I-140 on 08/08 to TSC.Now EB1B I-140 has been approval. I wrote a letter to NSC to ask relink. No response. So I want to write a letter to sentor or congressman to speed up my case. Could you share a sample letter to me? You also welcome to share your relink story with me.Thanks so much.
