The Trump administration has prioritized immigration policy, with new developments emerging on an almost weekly basis. Petitioners and applicants should approach the initial filing as though it may be their only opportunity to establish eligibility. The new USCIS policy, however, makes the distinction between filing quickly and filing completely important. Immigration policy is evolving not only through legislation or formal rulemaking, but also through policy memoranda, executive actions, agency guidance, adjudication practices, and litigation. The Aug. 5 USCIS policy update reflects that changing environment and carries a procedural message: applicants and petitioners should not rely on USCIS to provide a second opportunity to establish eligibility.
