You know, maybe there's a way.. concurrent h1b. Maybe all the h1bs "unionize" in the sense that they get to work part time for another h1b sponsor (the h1b union). Call this the H1B union corp. That way if they lose their official job, the h1b union they can stay beyond the 60 days to look for work.

I dunno, this would need an immigration lawyer to weigh in on. There's a YC one who appears from time to time.. This could be something YC does which would make startups more attractive to h1bs.
