Ask HN: How to solve US immigration for a foreign cofounder?

I have several offers to join a US-based startup as a cofounder/CTO. Hence, I'm trying to figure out a way how I can stay in US to work on my startup. I did some research and talked to the lawyers, and their seems to be no straightforward way to do this. To summarise, options are: - find a job, wait for H1B until Oct next year and then work on my startup part time - apply for a degree and study for 1-2 years, then have a year to look for a job without restrictions. Work part-time on the statup in the meantime - O-1, I'm not sure if I'm eligible myself, but I know some entrepreneurs who pulled it. I don't see a direct way to solve the immigration issue though. I think this should be a quite common case, so I'm curious how other hackers solved it. I'd really appreciate any legal hacks available, as the situation seems rather hopeless at this point.
