Support for Certified refurbished iphone X

If I will buy an iphoneX refurbished (certified by apple) from USA then it will come with an international warranty or not? For now, I will buy it from USA and use in the UK or India then in case there is any problem in the phone then apple store in the UK or India will consider that under warranty or will it be applicable only in USA?

Because if no international warranty is applicable then I will go with some lther option.
