No it's not. That model is NOT sold in the US at any Apple Store or authorized reseller.
Also, if you purchase an iPhone in the US and you don't live in the US, iPhone does NOT come with International Warranty. Should you have any issue with the phone requiring service or replacement, the phone will have to be physically returned (not shipped) to the US for resolution.
Buy your iPhone in the country you live and will use it.
