unlocked iphone 5s bought from Korea. Can I use in us?

Hello

I am planning to buy an iphone 5s locked in korea, but I will be returning to the states next month so I'm worried that it wont be compatible with all the lte issues, and carriers.

If I buy it in Korea, will I be able to use it in the US without any problems, as if I bought it in america ?

Thanks !
