Ask HN: How do you go from an L1/H1 to starting a startup in the USA?

1. Can you tell me more about your journey? What route did you use? Can all co-founders be previous H1/L1 holders?

2. In the UK it seem pretty straight forward, raise a seed, transition to a Tier 1 visa, start building. What would the Tier 1 equivalent in the States be?
