Do I claim a state of residence if I live and work overseas entire year?

I'm working and living overseas almost entire 2016, and may continue to be there for several years.  My family stay with me overseas.  I don't have any property in US, but have a valid driver license of MA.  I also keep a mail address there (my friend's address).  Should I file MA state tax return or file as a non resident status and don't file any state tax return?  Thank you.
