I built a mathematical model adopted by banks, but with no published papers. EB-1A?

It may well fit the EB-1A, yes. The category rewards extraordinary ability evidenced by recognized achievements, and there is no requirement that this recognition come specifically from published papers. A mathematical model adopted by banks is, in itself, strong evidence of practical impact.

The challenge, for those coming from industry or technology rather than academia, is usually translating that impact into evidence the process recognizes. The absence of papers simply means you need to demonstrate your relevance through other channels.

In your situation, the following tend to help:

• Documentation of the model’s widespread use by relevant institutions.
• Letters from recognized experts attesting to the originality of the contribution.
• Patents, awards, or presentations at leading industry events.
• Records showing that your work has influenced practices across the field.

In short, what matters is your track record of achievements and peer recognition, regardless of the medium used to share them. Since each case is evaluated individually, it is worth building an evidence strategy with a specialist and confirming updated requirements at the official source (USCIS).
