Thank you for doing this. My question is almost anti-specific - can you give a helicopter view of immigration processes - what is an H1B. Is that the only route in? what's the advantages and disadvantages? (It might help to say I am envisaging a similar AMA for a (different) partner who might explain pre-money valuations or best way to use SAFE or ways to find investors. I think I am interested in the general best practise if that makes sense?)
