The idea is a good one, but I'm wrestling with the dollar amount that needs to be invested before the founder can get a visa. Specifically, how likely is it that a US venture capitalist will invest $250,000 or more in a startup that's not located in the US (or Silicon Valley for that matter) vs. another startup that is?

Even if the non-US startup will move to the US once they receive funding, the largely intangible advantages bestowed on a startup in the Valley (which I've witnessed in the month that I've lived here) give it a better chance.

To be successful in facilitating the immigration of founders to the US, the founders' Visa should be available to any startup that has received any funding from a "qualified US investor" over $15K, which would include non-US startups accepted into YC.

And to avoid creating a huge immigration loophole (which seems to be the author's rationale for suggesting a "real money" cutoff), perhaps the Visa could have a clause that limits it to two years unless additional capital is secured and the startup is deemed to have "passed muster", at which point a permanent resident visa could be granted.
