As usual, having access to lots of money is the real hack here.
Also, I'm not your lawyer (or even a lawyer). But when someone says something like this....
> Think about the O1 as a fundraising process—it’s storytelling. You’re pitching the government on why they should invest in you long-term. Rather than “ticking boxes” with criteria, you need to think about how to structure the narrative so it’s compelling to the reader. The criteria and evidence, such as letters, support that overarching narrative.
...my spidey-sense starts tingling and I head for the door. The idea that you should "structure a narrative" when dealing with law enforcement (and immigration in particular) seems like just terrible terrible advice of the sort that could seriously mess up someone's life. I have a decent risk tolerance for some things, but this feels like someone telling you to douse yourself with gasoline and light a match[1].
[1] I mean, what's the worst that could happen? You want to be warm don't you?
The O1 is a visa for models, actors, artists, chefs, etc...
It's, in essence, a storytelling exercise whether you're Brad Pitt or the best pizza chef in Italy. They ask you to show why you're "extraordinary"
It's essential to make the Immigration Officer understand what you're doing. If all you share is true, it's not fraud in any way.
Lawyers aren't trained to understand what is a machine learning engineer and why what you're doing is important. USCIS agents don't know anything about tech and what YC is either. This isn't a visa for founders, it covers every talent category.
So it's on you to help them understand, to share the story.
Always consult a lawyer whatever you do, just help them out.
