That bill does not increase the number of employment-based immigrant visas/greencards -- it just eliminates the 7% per-country limit. In my opinion, it's a poor piece of legislation. The I-Square Act does a much better job at improving the terrible skilled immigration system: https://www.govtrack.us/congress/bills/114/s153

The best bill so far that Congress has introduced in the last ten years was S. 744 (113th Congress), which passed the Senate, but was blocked by then House Speaker Boehner (despite majority support in the House) under pressure from some racist and xenophobic far-right republicans: https://www.govtrack.us/congress/bills/113/s744
