I just found out that my ex husband is a registered voter in my states which implies that he received his citizenship. Based on the laws, if he receives his citizenship my case also should be upgraded to the immediate relative category. Would it be sufficient proof of his citizenship that he appears to be a registered voter? Obviously, I can't and won't ask him for his naturalization certificate. How should I proceed? Do I have to notify the Vermont Service Center where my original application went or the local office?
Any input would be appreciated.
