If you have bought directly from a US dealer, I can sure you that is US version.
There are three equipment of Autel to the top of diagnostic:
905 mini - http://www.auteltech.com/autelcms/Automotive%20Diagnostic%20&%20Analys/516.jhtml
908 - http://www.auteltech.com/autelcms/Automotive%20Diagnostic%20&%20Analys/458.jhtml
908 Pro - http://www.auteltech.com/Automotive%20Diagnostic%20&%20Analys/514.jhtml
The difference between 905 and 908 is only the tablet and in some countries it came with or without the old adapters.
The difference between 908 and 908 Pro is the VCI. With this VCI you could do coding & programming in BMW series F and connect to the OEM websites in order to coding & programming, if there ins't already available in your equipment.
I hope I could help you.
