The following pointers have emerged from recent cases and comments from USCIS:
1. Make sure you document the citation records (to show how many hits the journal gets), impact factor and circulation figures of the journals in which your publications appear.
2. (This we already knew) Recommendations from people who know you personally carry less weight than from those who know you by reputation.
3. Emphasize/document the "international" nature of your accomplishments.
Note: These comments have no application to physicians filing NIW through under served areas.
