What you observe, what you see in your city and what you see on the news might not be the best way to assess how unhappy or happy immigrants are to be here.
According to figures from the Department of Homeland Security, 1.05 million immigrants were granted permanent residence in the US in 2015.
Refugees (2015 numbers) 69,920 total: 12,676 came from Iraq, while 8,858 were from Somalia, 3,109 were from Iran, 1,682 were from Syria, 1,578 from Sudan and just 16 came from Yemen.
In 2015 the total number of Muslims 3.3 million (some are immigrants, some are citizens)
From NCSL:
Total U.S. population 319 million
Total foreign-born population 42 million (13%) (So far I can't find a happiness study on the 42 million though.)
I know this seems off-topic for this thread, but I think the implication (correct me if I'm wrong) is that you think Muslim immigrants are unhappy to be here, which (IMO) is on-topic because the man who did this wasn't American, and it helps to know the facts if we're discussing Muslims and terrorism and immigrations to the USA.

I'm not sharing this to argue with anyone. I know we're all upset about this attack and any terrorist attack no matter who is responsible. But if we know the facts maybe it will help us be less afraid. We can hope. I'm going to Europe in September and I'd be lying if I said I wasn't a bit afraid, and I've been thinking how to best avoid big crowds.
I wish there was a happiness study, lol.
Blue, I sincerely appreciate your contribution here and I don't get an argument vibe at all. The world has changed, seemingly abruptly, it's no wonder that we're reeling, trying to wrap our minds around it.
