Secondly, it is supposed to be used in a situation where the US parent company wants to transfer a member of staff from an international office.
I'm not sure to what extent the DHS look for the nuance of it being a US based PARENT company (which is not the situation you are actually describing) but I know that when international companies want to open US offices they often go down the E2 route, especially as they can then obtain visas for other employees of the same nationality. But that wouldn't work for venture backed startups due to the >50% ownership requirements.
On a personal level, this is also a crap visa route because you are locked to the L1 sponsor employer - meaning you would have to go home if you no longer were employed by the company (either by choice or by the company folding).
I agree it probably wouldn't be applicable in all cases, but it would cover a significant amount.
And as for the last paragraph: is anything different proposed for the startup visa? We're talking visas for startup founders here, not immigration shortcuts.
I don't think it's exactly clear what is being proposed with the startup visa but many other types of visa such as H1B contain a "porting" element which the L-1 specifically does not.
As far as I know, that's still what the VC guys backing this are going for, though I do know that folks like Kauffman, Vivek Wadhwa, and a fair number of others think this policy doesn't go far enough as, quote, 9 out of 10 successful startups don't raise outside capital, unquote. Still, it's an improvement in my books and seems well worth passing. The biggest issue is making clear to the politicians that this is an issue well beyond Silicon Valley, as Pelosi said that she felt the Startup Visa was too narrowly focused geographically, which of course it isn't.
I'm also collecting stories of affected entrepreneurs and the jobs at risk without Startup Visa to post on the new tumblr in preparation for a push during SXSW: startupvisa.tumblr.com
If you have a good business idea it will work outside the USA, therefore you don't need a visa to succeed.
With all these problems, It's pretty hard to actually build and sustain non B2B businesses in India atleast.
