So if I, an Irish citizen, founded a company with Americans employed or on the board I can apply to stay beyond my holiday visa?
Will be pitching like mad at YC NYC if this is the case!:)
Meetings are ok, AFAIK, as long as they are not for productive work, with some further caveats. Not that I want to dissuade you from pitching, but be careful there's nothing there to give the wrong impressions if/when you do decide to apply for a H1B.0
Not a lawyer, but I did get extensive coaching from an expensive immigration lawyer a few years back on what I could do (and how to describe it to US immigrations) while in the US, as I was traveling over every 2 months for meetings while we applied for a H1B, because immigrations understandably started asking more pointed questions when they saw my passport was full of stamps from the same US airport (never had a problem and they were always courteous, just probing more about my reasons for coming).
