I can speak for my own. Because it has taken me 7 years since my initial Green Card filing, I have had to put on hold several times the idea for a startup even though I see the tremendous talent around me who I can lasso together an idea, even if there are no earth shattering ideas at the moment. The right minds do not come together that often, ideas are actually quite cheap. And as I struggle myself with whether to create a startup on an EAD (the Temp Work permit before a GC), and potentially jeopardizing my GC, I see others around me going through the same pattern. And its frustrating to say the least.
Startup Visa should have been a reality long before Immigration became all mired down in the Illegal Immigration debate.
I have been lurking, reading on these forums till now, and I thought I should speak my mind on this topic.
