I like the charts but they doesn't seem to include the L-1 Visa path. Anyway it seems to me that this new reform rewards illegal immigration and doesn't do much to improve the chances of those applying for green cards through regular channels.

Also the travel restrictions for those with L-1 visas need to be reviewed, it doesn't makes sense that one you're approved with a L-1 visa in the US you need to go through another approval process in your home country if you want to travel outside the US.
