I changed my address online with form AR-11.

Last time I had to do this, they didn't have it online.

Is that all I need to do? I came in on k1 and now have unconditional green card.

I'm stressing out a little, I want to apply for citizenship soon so I don't want to make a mistake here....

Yes.

I called the customer service line a couple of AR-11s ago (I think I wanted to check what to put in the "my stay expires" section or something). A very earnest man told me that I had to fill in the form online and then mail a copy in as well, and I was just about to do so when I read the bit that said Please do not mail in this form. After a few moments of panic I went with the written directions, and am happy to say that I have not subsequently been deported.

Moral: don't expect to be reassured if you call the USCIS customer service line.
