I run a france-based company specialized in online advertising and I wanted to expand our activities to the US, who does not? Obviously France is way worst than Denmark and the US for business, tax and work laws, so I can't really relate for the tax part.
I relate mostly for the visa stuff. What I am getting from the OP post, Nitai was doing L1-A. I have been doing L1-A too. (I recognized the list of documents scanned the OP has posted! :) ) Same hassle, same huge amount of documents needed, we didn't give up though after the first request for evidences but the requirements are kind of high so we finally didn't get it.
US now sucks for immigration and it seems to worsen. BUT, Europe seems harder too than before for immigration. It seems a tendency that in the world with Internet, cheap transportation and desire for better file, people immigrate more and countries make stronger bureaucratic walls.
That's sad. :'(
