Timeline and documented change
The final rule appeared at 89 FR 6194. It adjusted certain immigration and naturalization fees and expanded certain humanitarian exemptions. The announcement date, Federal Register publication date and effective date are separate milestones. This was a final rule, not simply a proposal.
What to check now
Use the current USCIS form page, instructions and fee guidance before filing. Do not use an archived announcement as a live checklist. If an edition, fee or supporting-document rule has changed, the historical event remains part of the record but is not a substitute for today’s requirements.
