Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
It will "work", but some providers may block their service there. It may also be confused since your account was created in one country and you're using it in another. You may be better off creating a new account once you get there and then performing a factory reset to link it to the new account. There's no good way to know what will happen once you get there unless someone here has done the same thing.
