A Selective Service issue usually turns on age, immigration status, knowledge, willfulness, and whether the applicant can document the timeline clearly.
Use this as a planning checklist, not as legal advice. The exact response should match your USCIS notice and personal record.
No. It means USCIS wants clearer evidence before deciding. The response should match the exact request and avoid unsupported explanations.
Usually no. A better response is organized, labeled, and tied to the RFE wording so the officer can see the timeline and proof quickly.
Before responding if the issue involves criminal records, taxes, Selective Service, possible misrepresentation, or a short deadline.
