Yes, but it may not work with LTE depending on the carrier you select.

The carrier (national) options in the US for using an unlocked GSM device are AT&T and T-Mobile.
Both AT&T and T-Mobile use different LTE bands than carriers in other parts of the world.
LTE will not work on your unlocked iPhone.
Also, you will be unable to get any support for that device in the US should anything go wrong with it. Warranty and support are only valid in the country of origin.
