As I live overseas and always file married Jointly. Spouse green card has expired yet still has a ss

You can still file jointly reporting both of your total worldwide income on that return since they still have a valid SS#.

Thank you so I can classify my spouse as a US resident for tax purposes as we file Married Jointly? Appreciate the clarification and thanks for your support

Yes, for federal tax purposes you can treat your spouse as a US Resident. 

Thank you for taking the time to provide me this clarification. Best wishes to you
