# Support letter outline (supervisor or collaborator)

_This is a structure only. The signer must write the letter in their own words and sign only what they know and believe._

## 1. Who I am
[TODO: signer's name, title, institution, and credentials relevant to the field (attach CV)]

## 2. How I know the petitioner's work
[TODO: the working relationship, its dates, and what the signer observed first-hand]

## 3. Specific contributions
[TODO: 2–3 concrete contributions, each with what it changed and who used it; cite the paper, patent or product]

## 4. How the work is used by others
[TODO: examples of adoption, citation in context, or influence the signer knows about]

## 5. The proposed endeavor
[TODO: the endeavor exactly as filed]
[TODO: why the signer believes the petitioner is well positioned to advance it, with specifics]

## 6. Signature
[TODO: signature, date, contact details]

Avoid: general praise (“hard-working”, “excellent”), EB-1A phrases (“extraordinary ability”, “top of the field”), and claims the signer cannot support.
