Thanks for posting.
You will surely received exact insights from experienced members.
As for me,the fact that you are still a green card holder under IB6 ( approved vawa as a spouse or former spouse of a US citizen) qualifies you for filing the N-400 under three years rule.
But don't know whether your current marriage status nullifies it.
