Summary
The short version before the detailed checkpoints.

Form I-140 is used for several employment-based classifications, but the required evidence and petitioner context differ. A useful preparation file makes the requested category, source documents, and unresolved filing questions easy to audit.

Review checkpoints
Open the sections you need instead of scrolling through every paragraph at once.

Start with a one-page classification brief naming the category counsel should evaluate, the proposed petitioner where relevant, the intended work, and the threshold requirements that need documentary support.

EB-2 NIW, EB-1A, and EB-1B may use overlapping documents, but they ask different questions. Label why each document is included rather than assuming a strong CV answers every category-specific requirement.
