An EB1A letter should force four facts onto the page:

1. Name the distinguished organization or project.

2. State the work you owned and why the role was essential.

3. Give the measurable result.

4. Point to an independent exhibit that proves it.

For original contribution, show adoption or use beyond your employer and the consequence for the field. Praise without corroborating proof leaves the officer with an assertion.

Your cover letter should connect each claim to the exact exhibit and page.

If you are building this packet, DM your current stage and two strongest criteria. I’ll map one claim-to-evidence row with you. Educational only; counsel handles legal advice.
