Sadly, I don't think it will because the bands are different. It looks like you might only get 2G according to the bands listed here: Amazon.com: Microsoft Lumia 550 8GB Factory Unlocked 4G/LTE - UK Version with No Warranty (Black): Cell Phones & Accessories

Your best bet would be to get it from B&H when it comes out, since that one will work on AT&T (and T-mobile). Right now, you can only preorder from bhphotovideo.com though. I have links to preorder in this thread here : http://forums.windowscentral.com/microsoft-lumia-550/400099-b-h-photo-listing-550-$149-99-a.html

It has the same bands as my 930 UK version so no you won't get LTE (4G) on AT&T.

I was able to get H+ (HSDPA Plus) maximum.
