@AT20000 divorce periods vary by state. Not all take a year.
I understand what you're talking about. But I'll let you continue with your path of high resistance.
You must be new to VJ and immigration. There's fairly a good amount of people who divorce as soon as the first GC, whether 2 or 10, land on their hands. If 2, theysuccessfully ROC. USCIS understands that sometimes marriage doesn't work. Do you know that with divorce, you don't need to wait for 2 years to file ROC? You can file immediately you get the divorce certificate. And if you're in a state with short divorce time eg Texas, or even in a state that takes long BUT you can project when your divorce will be final, you can file ROC with the divorce filings for the court and by the time RFE comes, you have the divorce certificate and all you just do is submit.
Once again, you took a high road for no reason. What happens if you don't have proof of DV? Or USCIS asks for more? On one hand, you have 1 divorce certificate while on the other you have mountain of papers. What do you choose?
Additionally, not sure where you read that if you file with DV, USCIS isn’t allowed to talk to your ex-spouse. Do you know peoeple falsify things? DV can be falsified. Happens when people are trying to VAWA. DV or divorce, USCIS can talk to your ex. What makes you think that your story is the only truth? It can be the truth OR as I said regarding some VAWA cases, you probably were using your spouse and got "help" from your community on documenting things so as to get out of the marriage ASAP since you already got a GC.
Once again, you took the long road for absolutely no reason.
You have a divorce certificate but choose to not use it and go the high road. Only reason I see of why you did this is to get N400 earlier. That's your main reason. You're just lucky it's election time and approvals are coming quick, otherwise, you'd probably be waiting 1.5 years to receive word from USCIS, only maybe for them to tell you "sorry, add us more documents." Then you're are in endless loop of USCIS juggernaut. So, that fast citizenship that you were chasing now isn't coming. Now, wouldn't it have been easier just to use your divorce certificate? Divorce certificate itself doesn't require additional proof. The one proof required is for entering marriage in good faith. DV itself requires proof + the good faith items. So, if you have divorce certificate, why not use it and eliminate potential USCIS asking more stuff later? You're not the first immigrant I've come across trying to PROVE their sainthood.
And check ROC timelines outside election time. They're 1.5+ years.
Read and understand what @Boilerwrote above. If you don't understand, ask him.
I'm out. Good luck
