USCIS Evidence Index and Exhibit Labels: Examples and Checklist

What an evidence index is

An evidence index is the table of contents for your supporting documents. It lists each exhibit by its label, says in a few words what it is, and gives the pages where it starts and ends. Exhibit labels are the matching marks on the documents themselves, so the officer can go from the index to the page in seconds.

USCIS does not require a particular index or labeling system for most filings, and the I-130 instructions do not require a cover letter. These are organizational conventions. They are worth using because an officer may review hundreds of pages, and a clear index helps you check that nothing is missing.

When an index is most useful

• Any filing with more than a handful of supporting documents.
• Employment petitions such as EB-2 NIW and EB-1A, where evidence is organized around legal requirements.
• RFE and NOID responses, where each concern in the notice needs a clear answer.
• Interview packets, so you can find a document quickly when the officer asks for it.

Practical numbering conventions

• Use letters for exhibits (A, B, C) or numbers (1, 2, 3). Pick one and keep it.
• Number documents inside each exhibit: B-1, B-2, B-3.
• Number pages continuously across the whole packet, so the index can say “pages 41 to 46.”
• Put a short label on every page, such as “Exhibit B-2, page 3 of 6,” in a corner where it covers nothing.
• In an RFE response, either continue the numbering from your original filing or start a new series with a different prefix, such as R-1, and say which you chose.

Sample index: marriage green card (I-130 and I-485)

A hypothetical couple, shown to illustrate the format. Descriptions say what the document is and what period it covers.

Sample index: EB-2 NIW

A hypothetical engineer. The index follows the legal structure of the petition, so each section answers one question.

Sample index: EB-1A with cross-references

A hypothetical researcher. One document can support more than one criterion. Give it one exhibit number and cite it wherever it applies, rather than printing it twice.

Descriptions and cross-references

A good description lets the officer know what a document is without opening it: who issued it, what it shows and the period it covers. “Bank statement” is vague. “Joint checking statements, Chase, January to June 2026” is useful.

When a document supports two points, say so in the index, for example “also cited for criterion 5.” In the response letter or cover letter, cite exhibits by label and page: “See Exhibit C-1, page 42.”

Common labeling mistakes

• Labels in the index that do not match the labels on the pages.
• Page numbers that restart in each file, so the index cannot point to an exact page.
• Labels that cover a date, a signature or an account holder's name.
• Several exhibits with the same letter after a late change.
• The same document printed under two exhibits instead of cross-referenced.
• Vague descriptions such as “Misc. documents.”

Keeping a large packet understandable

Group by what each document proves, keep one numbering system, add a cover page at the start of each exhibit, and keep descriptions short. For online filing, upload each exhibit as its own file where the form allows, with a file name that matches the label.

Case Album builds the index, a cover page for each exhibit and a label on every page for you, in the marriage album's Complete Evidence Package, the NIW and EB-1A packets and the RFE response organizer.

Do I need a cover letter?

Not for an I-130; the instructions do not require one. Some people add a short one, especially when mailing. Keep it simple: who is filing, which forms, and a list of what is inside. For RFE and NOID responses, a response letter organized by the notice's concerns is common practice, with the notice itself on top.

By mail, follow USCIS's mailing tips, which say not to use binders, photo albums or scrapbooks.

This is general information, not legal advice. Check the current USCIS instructions for your form, or ask an immigration attorney about your own case.
