Yep signing that you understand the oath and willing to take it

I believe this can be true. OP was probably asked to sign oath of allegance to ensure they're happy to take full oath without modifications. I signed it too if I remember correctly. But it's more of "I agree to saying this as is" VS actually getting approved or taking oath.

It clearly asks to answer this if marriage ended due to divorce or death.

All I-129F fiance petitions are processed by California Service Center as far as I know.

Was certificate short form or long form version? If short version was sent this could explain at least why they're not happy about sponsor's documentation. As for beneficiary, do they live in the country of their birth and citizenship or let's say they're Nigerian citizen living in the UK?

Unlikely going to help. USCIS does not provide legal advice. When you called them, you get "welcomed" by a robot, which is difficult to bypass. When you finally speak to a person (phone or chat), it is a low wage hourly worker who has no clue what they're talking about. And the worst part, they make up answers to finish your call or chat sooner, so they can take next person's question improving their performance for statistics. I would try getting more traction here or even employing a lawyer. The reason I didn't give advice of what to do, is because this may be more complex than what it appears to be. That's why I asked where the petitioner was born etc. Because it seems like USCIS for whatever reason is not convinced they are a citizen. Wrong or incomplete reply to RFE may result in petition denial, e.g. time and money wasted.

What is your partner's citizenship? It's not based in residency

You get instant confirmation when filing AR-11 online. It's a page you see instantly after submitting it. You can do it again safely Sponsor needs to file I-865 by mail too

This is still not helpful. There is probably more text preceding this sentence explaining why it wasn't enough? Was the US citizen born in the US?

Can you please post exact RFE wording, redacting any sensitive info? What evidence of US citizenship was provided with I-129F submission?

4-8 weeks on average I'd say if don't hear anything, arrange InfoPass and get ADIT stamp beginning of December.

I did. Wasn't needed, but it's like insurance policy. If officer asks or says "I don't have your evidence", you have it.

Everybody has to have an interview in local field office for N-400 based on where they live. This applies to people who file in paper and online. Best of luck!

There's no such form as 1-130, there is I-130. Does you new income qualify based on 125% of poverty guidelines? https://www.uscis.gov/i-864p Otherwise, Lil Bear posted useful diagram

Not for majority It is related, yes Hard to tell, but at least few weeks, most likely few months.

You realize things are not send letter by letter for each case between USCIS and NVC? There's a pile of cases stacked at USCIS and once in x number of weeks a truck comes to collect it all and load on plane etc? So from USCIS officer perspective, once they completed job on case and dropped the case in mail room for sending to NVC, they sent it. But it make take few weeks before actual truck comes to pick it up and transport it on plane etc. Same with receiving. The mail may sit for some time at NVC in mail room, but they only receive it when somebody actually opens the letter. I understand the frustration, but none of this process is quick or easy.

You can do it, but I wouldn't. Marriage certificate is required initial evidence. You may receive RFE slowing down the case if not provided at time of submission. Other docs may cause misunderstanding / delays. Others can correct me. This is not a legal advice.

Don't bother. This is mainly for correspondence to other countries that don't use Latin alphabet

I can guess was too married for K-1?

Yes, unlike first receipt notice printed on watermarked paper, both interview and oath notices are regular black and white without protection and can be printed off myUSCIS if needed.

You should receive both physical letters as well as digital copies in myUSCIS account

Neither. There is 2 year conditional or 10 year uncoditional green card. There is no 3 or 5 year green cards.

Fraud prevention or to avoid accidental use? Not all CBP pay attention to dates and stamps, though they should

Congratulations! Very nice of them to give a reminder, but I wish they would just tell the truth - you need to go to SSA, the check box doesn't work for sure. Whoohoo!

I would not travel with denied I-751 / N-400 unless absolutely necessary. And knowing you may have pain coming back even with the stamp.
