Samsung Tab S2 International vs US version

Hi, I hope I'm asking this question in the right topic area. If not I apologize. last week I bought the Samsung S2 9.7 inch from Newegg. I think it might be the international version since it will not be release in the US until September 3rd. I'm working if people usually work on ROMs for international or US versions of a device? I'm not sure if these two version will be able to use the same ROMs. Thanks.
