Why not a mail-order spouse programme for founders? Surely there must be a lot of Americans, especially with the financial crisis, who would be willing to take a bet on a founder's future income in exchange for a green card. You could make proposal pitch decks with Lessons Learned from previous marriages.
And if it doesn't work out there's always Series B.
In all seriousness, I always find these discussions about immigration baffling in part because my dad was career military and so was my ex husband, so I have known a great many people who immigrated to the US by marrying a soldier (mostly foreign women marrying American men). In some cases, there was a lot of paperwork and all that, so it wasn't always smooth and easy. But I have spent most of my life surrounded by immigrants who never dealt with the types of immigration issues that routinely get discussed on HN. I know someone who wants to immigrate and I find myself frustrated with not knowing how to help them because this type of immigration is so alien to my life experience and I just don't know where to begin. Some part of my brain cannot comprehend why on earth this should be so hard. It so doesn't jibe with my personal experiences.
