"Support subscription"? For Roku support or are you speaking of a subscription to Hulu? Roku themselves don't offer a "Support subscription", so I hope you mean a Hulu subscription. In general, you can move Roku devices anywhere in the country and nothing will change. Lots of people travel with a Roku player all over the country. If you're getting local channels through Hulu TV then you may have to update some information with Hulu, but questions concerning a Hulu subscription are best handled by Hulu even if you're paying through Roku.
