While we're on the topic of conferences that target a specific slice, does anyone know if there's something like an Immigrant Founders Conference? That sounds like another demographic that has huge potential and could use some pretty specific kinds of help.
Joking! As an immigrant founder, I can think of a couple of key issues may have been different for me than a resident founder: immigration laws and their impact on startups (obviously) and to some degree, context - understanding customers well, even when you did not grow up in the same context as them.
I imagine, if nothing else, non-naturalized immigrants have unique concerns and obstacles. Visa concerns, ITAR (admittedly probably rarely an obstacle for YC style startups), etc.
I can't say I have any personal experience with any of that though, that's all just a guess.
I don't know about immigrant founders conference, but the most prominent push between immigrants and tech sector would be FWD.us movement. (edit: it should be .us not .org)
