Remember, H1-Bs and immigrants, that a union would be not be on your side. They would have a large percentage of pro-nativists that affect their policies, regardless of what they say officially. There's a long, long history of unions in the United States opposing immigrant labor that is worth reading up on and, even on supposedly worldly and well educated HN, you will see that there isn't much pushback against posts with anti-H1-B sentiment.
