Thank you so much for the advise. I wrote an explanation letter to NVC and also attached my Indian passport surrender certificate. My case is documentarily qualified. Now just waiting for interview. Thank you again.
Are you still residing in India? If not, upload a letter to CEAC, stating that the expected format for Indian police certificates is not available for foreign nationals not residing in India. Include a screenshot of the DOS Reciprocity page for India, highlighting this line from https://travel.state.gov/content/travel/en/us-visas/Visa-Reciprocity-and-Civil-Documents-by-Country/India.html -- "Police certificates are only available for Indian nationals and non-Indian nationals currently living in India. Indian police certificates are not available for foreign (non-Indian) nationals applying outside India."
