He's an Indian H1B, or likely was an H1B. Here's a bit on his background:

In the several articles I skimmed, I do not see mention of his current citizenship, so likely still Indian. Doesn't seem relevant to the whole matter. Left a suicide note. Will be interesting to hear the contents.

Gun free zones. Those are working quite well for crazed gunmen.

Almost certainly an H1B. And just as certainly that's why his personal details are not being discussed in the 5th Column press.

H1B is a work visa that allows U.S. employers to temporarily employ foreign workers in specialty occupations. Sarkar was likely here on a student visa, an entirely different matter from an H1B.

Did he overstay his visa? Did he have a green card?
