What is the Index Score on each Washington listing?

The Index Score is our own internal rating built from five equally weighted components: experience, credentials, client feedback, responsiveness, and profile completeness. We publish it as a band — Exceptional, Strong, Established, or Developing profile — plus the firm’s rank among scored firms in this metro, not as a point total. It is not an advertisement or a paid placement: firms cannot buy a higher band, and the components are published on every firm profile.

Can a Washington firm help if my case is stuck at USCIS?

21 firms on this page file mandamus and Administrative Procedure Act suits in federal district court to force a decision on delayed applications. Filter by "Files federal delay lawsuits" to shortlist them, then ask in the consultation how many such cases they have taken to filing.
