Valid H1B - NIE eligibility

Hello all,
I have a valid H1 B visa and am currently in the US.

I lost my father on May 14th and could not travel then. I am planning to travel to India in the last week of July.

Can you pls suggest the steps to request for NIE? Can I initiate and get NIE approval before I leave for India? Pointers are highly appreciated.

You can check at below link if you qualify for NIE, if yes it also explains how to request one from the consulate that issued your H1B visa.

Thank you Kalpesh. Appreciate your pointers.
