Also it's not generally possible to get venture funding for a US based startup while still in another country. A VC would not want to add "immigration policy risk" to the extensive list of risks she already takes when investing in a startup.
Secondly, assuming you are already here on an H1B working for largeco (as I am), it is also not possible to start your own startup without 1) Having an American cofounder 2) Raising funding and/or getting a large number of customers
Getting customers before you start working on a startup is of course impossible and raising funding before you start working on it full time is also really hard (unless you are already a superstar in your domain of work).
So, really, on what basis are you calling people who want a simplified process lazy?
