There are plenty of people who are trying to become American, as well. My wife came here from Iran to study at an American University, and her conditional green card is set to expire next year. We want her to get her citizenship as fast as possible. Now it seems that USCIS has put all that on pause though, so we're sweating bullets over whether they'll actually let us file the petition to have the conditional aspect removed in a year's time. If they don't, we're fucked and all of the work and money(read: thousands of dollars) we put into putting her through the system properly will have been all for nothing. FYI I'm an American citizen.

There are per-nation limits on the number of green card holders that can become citizens every year. Maybe they want to be citizens, but aren't allowed to be?

Meanwhile, a lawyer friend of mine had to advise a client of his not to go home to visit his dying father, because he might not be allowed back in. He's lived in the US for twenty years. He owns a business that employs six US citizens. He won't get to see his father again, and a father won't get to see his eldest son on his deathbed.

So yeah, be smug. Enjoy that.
