There's a limit to the number of green cards that can be issued for people from a particular nationality (country of birth than country of citizenship). This creates a backlog for Indians and Chinese nationals. The backlog causes a long wait time and uncertainty for Indian nationals. There are people, like me, who have been waiting for their green card for more than 7 years. I've been in this country for 15 years now, have a Masters degree and have paid more than half a million in taxes (a couple of acquisitions helped). With equity, I make close to $400k/yr and could probably make more if I had a green card. I have substantial (north of $250k) savings in cash which I hesitate to invest here since I've no idea if I'll get my green card or be sent back. My spouse was finally allowed to work here due to Obama's H4 EAD rule but now that's going to be revoked too. It sucks, since my spouse wants to teach kids with special needs and there's significant demand for such teachers. If my green card doesn't come through in the next couple of years, I'll most likely move back to my home country or one of Canada/New Zealand.

I guess I misread your earlier comment, I thought you were talking about Australian immigration policies to the parent commenter who was an Australian.

My bad, since you are talking about US, yes I agree with you.
