Does “I Support This Petition” Weaken an EB-1A Expert Letter?
A sentence like “I support this petition without qualification” probably does not make an expert non-independent by itself.
Independence turns more on the writer's relationship to the petitioner and the factual basis for the opinion than on one closing line.
I would still remove it.
It adds little, and it gives an officer an easy way to read the letter as advocacy. The writer should explain what the work changed in the field, not announce the legal outcome USCIS should reach.
Use this five-part check instead:
1. Writer standing
Explain the expert's role, relevant expertise, and why their judgment matters for this specific contribution.
2. Relationship
State how the writer learned about the work. If there was no collaboration, reporting relationship, or financial interest, say so only when it is true.
3. Specific contribution
Name two or three contributions. Avoid broad statements about talent, promise, or deserving approval.
4. Independent corroboration
For each contribution, point to adoption, reliance, citation, commercial use, an implementation record, a benchmark, or another source the officer can verify outside the letter.
5. Field-level effect
Explain what changed and why that result is unusual or significant in the field.
A stronger closing pattern is:
“Based on [specific contribution], [independent use or result], and [the writer's basis of knowledge], I consider the work to have had [specific field-level effect].”
Do not copy that sentence blindly. Replace every bracket with a fact the record can verify.
USCIS guidance emphasizes specific contributions, significance to the field, and the writer's basis of knowledge and expertise. That is the job of the letter. It should help the officer verify facts, not manufacture independence or impact that the rest of the record does not prove.

Buy it only if evidence organization is the bottleneck. It is an instant-delivery, no-refund digital product. This is educational information, not legal advice; counsel should make the final wording and filing-strategy call.
