To clarify: You can apply for citizenship, as the spouse of a US citizen, 3 years minus 90 days from the time you became a Green Card Holder. That applies to those who entered the US via a spousal visa as well as those who adjusted status.
For those who are not spouses of UC citizens, it is 5 years minus 90 days.
The only thing you can do is to check the USCIS status until NVC gives you the DOS case number. USCIS automatically sends I-129fs to NVC. It might take a short while.
USCIS will automatically send the case to NVC. NVC will assign a DOS case number, inform you, then send to the consulate when they (the consulate) requests it.
I am sorry that you are experiencing this. Have you written to the consulate and explained the entire situation? I find it strange that the consulate would deny the B2 based on these circumstances. Perhaps you US Senator could provide some help.
Please ask additional questions about this matter here in this thread. You are now asking if you need an attorney, correct?
People have successfully filed Removal of Conditions without an attorney. A consultation might be a good idea since these cases are usually scrutinized by USCIS. As @SteveInBostonI130 stated, you will also need your final divorce decree to file the I-751 with a divorce waiver.
Option 2 is "Married- Filing Separately"...not single.
You summed up the situation pretty well. I would choose option 2. When I filed MFS in 2015 & 2016, no software package would allow filing electronically using the "NRA" annotation. I think that has changed.
Calling tax expert @Wuozopo
I assume that is the case. The Dallas office (in Irving, actually), conducts ceremonies in multiple places. There are a LOT of new citizens naturalized around here.
Yes, it is. Our I-751 was at MSC. Took 44 months to approve it. Unfortunately, that is the reality now. I would just plan on filing an N-400 as soon as you become eligible.
Since USCIS is now issuing 48 month extension letters, long waits are expected to continue.
