Endeavor is narrower than your field
USCIS distinguishes between the field you work in and the endeavor you propose. 'Artificial intelligence research' is a field. 'Developing and deploying machine-learning models that detect equipment failures in municipal water systems' is an endeavor. The second one can be evaluated for merit and importance; the first cannot.
- Name the specific problem you are working on
- State what you will actually do about it in the United States
- Identify who benefits — an industry, a patient population, a region, a federal priority
- Describe the scale and how it reaches past one employer
