The bill offers up to 140,000 green cards per year to college graduate Indians who agree to take white collar jobs — in many industries, and at low pay — from American graduates. There is no legal limit to the number of Indian graduates who can compete for those employer-provided green cards by using OPT, H-1B, L-1 or B1 work visas to take Americans’ jobs at lower wages.

Aside from Perdue, no other GOP or Democratic Senator has risen to defend America’s millions of college graduates from Lee’s green card giveaway. Kentucky Sen. Rand Paul ended his July opposition after getting a deal favorable to his donors. So the only objection on September 19 came from Perdue.

But Perdue is now is under intense pressure to quit his opposition and let the major donors hire more low-wage Indians instead of the young graduates in his home state of Georgia.
