we provided a full size manila envelope (self addressed to us) so the naturalization document was not folded 
some have paid a fee with the passport application to pay for this
our 3 documents came back in 3 separate mailings  with no damage

I was just reading off of their website, for emergency passport it says to call them (in bold even). 
 
https://travel.state.gov/content/travel/en/passports/get-fast/emergencies.html

They won't give the tracking # for onward journey even if you paid expedite .there will be a 7-10 day from the time you applied in USPS to be able to track in the system . There is nothing I believe we can do in between to trace it .

While you might be concerned, this is what is required. You must give them the original certificate and you must apply in person you cannot mail anything in. 
 
I got a money order at USPS to pay the fees so I paid for everything using my debit card. 
The passport tracking site uses regular biographic data DOB, your social and name so you don't need a tracking number. When they are returning your passport you get a tracking number. There's no tracking number for the return of the certificate. 
 
I also got my photos at USPS. It was just easier for me to get everything done there. 
 

Hello VJ members,
 
Hope all is with you guys!
Need help from folks who have already applied for US passport after Naturalization. My understanding is that we would need to submit Original Naturalization certificate ,DS-11 form, Driving license (photocopy) color passportsize picture along with $110 dollars fees. If we need to know submit original Naturalization certificate, I am afraid they will lost it just like they have lost my I751 greencard and still they could not find it? Also, Why do we need to make photocopies of these supporting document if they have already asked us to bring original copies?
 
How do we have to pay $110 fees through pay check payable to "U.S. Department of State" right? And also would USPS accept passport size picture from lets say CVS/walgreen (if I chose to use their passport size picture services) or I should just stick with USPS passport size picture services? Which one serves better? USPS would charge $35 as passport acceptance fees, does that include passport picture or USPS will charge us extra fees for pictures?
 
Last, how long does it take to get US passport and original Naturalization certificate?
 
Thank you all for help and advise?

I applied on March 18 (expedited) and got my passport back on April 9th. But no sign as yet of the certificate. I suppose strictly speaking I no longer need it because I have the passport but I’d like some idea of when I should contact them about this. And in fact, who should I contact? Applied in PA, passport came from Little Rock.

Ok I know what u mean but legally the marriage is still valid and emotions does not matter at this points as I mentioned this could end either way i.e., we may end up together or get divorced. And I'm sure, at the ceremony,  io is not going to care if I tell him we are still living together not separated or divorced, but we are having verbal arguments and visiting marriage counselor which is the truth and I don't mind revealing it to the io if he asks. But I can't just not show up to the ceremony because I think we are going to rough patch and not sure what will be the result. 

Hello!
I would recommend taking ALL documentation with you, I would personally even take the green card paperworks, since IO can always rise a question about it and you've better want to be prepared than not having that info with you. I took all my info and had it organized from latest to oldest and my IO was very pleased I did that, I separated everything with colorful tabs and believe me, she went through everything. I read the VJ experiences and you know it pretty much said 90% of the times is super smooth interview and that they even hardly look at your paperwork, well that wasn't the case for me and I'm glad I did my homework and went prepared. For my citizenship I took my last 4 year taxes with my husband, the paperwork of our house purchase, the cars and motorcycle title all under our names, old leases we had at places we rented, electricity, garbage, water bills, etc etc. 

From my experience with the Portland OR office, I know they offer same day oaths but it is entirely up to the IO decision... I didn't complain, I received my Oath ceremony date two weeks after that  and they gave me my naturalization certificate that day.  Good luck and let me know if you need any extra info. I will post my experience here:


 
      Posted April 13 (edited) Good afternoon guys,
I had my combo interview yesterday April 12, 2021 at the Portland, OR office and I thought it would be important to share my experience with the VisaJourney community that has helped me so greatly! ♥♥♥♥
--------------------- I applied under the 3-year rule -----------------
◘ March 5th: Interview was scheduled for 12Apr2021 @ 8:40am
About the date of the interview: ◘ Got in the building 15 minutes earlier. I was wearing high heels and they made me take them off, lol. I went in with my husband as my I-751 application stated it was mandatory he came with me.
◘ I was the 3rd person to get in the building. At 9:05 my name was called, the Immigration Officer asked us to follow her to her office. She was serious and quiet, I kind of wished I had other Immigration Officers, they looked way more easygoing? Who knows.
◘ Once I was sat there I could tell she had a huge pile! She explained it was everything the government had on file for me, since my K1 fiancee visa was submitted (back to 2016!)
 
     1.1. The Removal of Conditions Interview (or I-751)
     1.1.2. About the relationship:
 
She asked me and my husband:
– Where did you meet?
– When did you meet?
– Where do you like to vacation?
– What are your favorite activities as a couple? We got talking about snow, skiing, Idaho, Wyoming, etc. It was a fun topic.
– When did you guys marry?
– When was the last time you visited her country (Peru)?
– Did you bring with you any additional evidence since  you last file for your ROC (I-751)? Oh yes, sure thing, I had brought with me 6 big files in those huge folder, containing last 4 year taxes, last 4 year bank statements, utility bills, house deed and the whole stack of purchase info (as we bought a house), titles of both of our cars under our names, health insurance which states my husband is under my insurance, dental insurance, photos, 401k information, life insurance. She looked it at all!!! Big FYI. She was extremely thankful I was so organized. I used colorful tabs for all of my info. Taxes were in one folder, bank statements in another and so on.
– She then excused herself for taking some time to "enter" some information in her computer. She took like 5-7 minutes, we were just like looking at the wall when she said "Phew, ok, I'm done, you case looks solid, I'm recommending you for approval. We will move onto the N-400 application". She turned to my husband and said he can stay or he can leave for that portion of the interview, either way, he was welcome to participate. He decided to stay.
 
     1.2. The Citizenship section (or N-400)
I can say this experience is a standard as it can get. I've read past experiences and they are all same Modus Operandi:

– I was asked 6 questions, I got them all right, she stopped right there. They were as follows:
♢ What do we call the first then amendments to the Constitution? The Bill of Rights.
♢ What are two rights in the Declaration of Independence? Life, liberty and the pursuit of happiness.
♢ If the Presidente can no longer serve, who becomes a President? The vice president.
♢ When was the Declaration of Independence adopted? July 4, 1776.
♢ What is one thing Benjaming Franklin is famous for? U.S. Diplomat.
♢ When do we celebrate Independe Day? July 4.
– For the oral exam, I was asked to repeat after her "What state has the most population?"
– For the writing exam, I was asked to write in the pad: "California has the most people". 
– She went through all of the Yes/No questions (terrorism, international organizations, if I had commited any crimes, etc. etc.)
– Officer mentioned I had approved and the last step is the Oath of Allegiance, I should get a letter in the mail and on my online account stating the details of the ceremony. She said I should get a reply from them in a month regarding date and time, no more than that. If that did happened, I should get a hold of them.
– I asked regarding Same Day Oath ceremonies and she said they still do offer them, but only for those who had driven 4 hours or so, not for locals. I thought it was a lame excuse, we were so few of us, I would dare to say only 6. But anyways, I was of course thankful and left the room.
 
**Important: I had done a Change Of Address at the time of my Naturalization Application, but it looks like they never got it. they still had my old address on file, thankfully I had brought with me the screenshot of when I changed my address through "My USCIS" and the confirmation letter they had sent me. She looked surprised. You have to go as confidente as you can!
***Important: She asked to drop off GC, Advanced Parole and Employment Card when taking the Oath. Do not forget!
 
Last update: Checked my account this morning and the N-400 says "Oath Ceremony Will Be Scheduled". Patiently waiting here. Almost there. 

There might be some details I left out that I currently don't remember? I apologize.
If any of you have any questions, please don't hesitate to go ahead and ask me.

Hello! 
I'm sorry I'm just now reading this. I remember in my folder tabs, I sorted it by dates, the documents containing the latest goes in the front and so on, way over in the back I put my original AOS and N-400 applications.  
So when she asked about the updated supporting documents, I handed her my latest info and just in case I said "I have more, but it goes back all the way as to when I applied, lol", she laughed with me and said that was good to know.

Good luck! You'll do great.

Hi Mathasofi:
 
Thank you for sharing this information! it's really helpful.
I wonder when you were asked for "any updated supporting documents for your marriage?", did you just hand over ALL documents for the entire marriage, including those you've submitted initially for your I-751/N-400 packages? or just the actual updated portion that were not included in your initial I-751/N-400 Package?
 
I am preparing my document folders, and not sure how should I better organize them.
 
Thank you!!!

All done with the interview! Honestly it felt like an informal conversation. The officer noted that I didn't seem nervous or that if I was nervous, it didn't show.
 
Now to wait for the oath ceremony to be scheduled.

Thanks @marthasofi and @Gordo2
I applied in early Nov 2020 and got my biometrics reuse in December.
Since then, the wait time estimation calculator has simply been all over the place and I think the site is also acting funky these days with changes in the way info was getting reported.
 
Fingers crossed, I get an appointment in June or July (assuming 8-9 month wait).....

I'm a 5 hour round trip (with no traffic) from Portland and wasn't offered a same day ceremony. I guess they're thinking of people from eastern and southern Oregon.

– For the oral exam, I was asked to repeat after her "What state has the most population?"
– For the writing exam, I was asked to write in the pad: "California has the most people". 
– She went through all of the Yes/No questions (terrorism, international organizations, if I had commited any crimes, etc. etc.)
– Officer mentioned I had approved and the last step is the Oath of Allegiance, I should get a letter in the mail and on my online account stating the details of the ceremony. She said I should get a reply from them in a month regarding date and time, no more than that. If that did happened, I should get a hold of them.
– I asked regarding Same Day Oath ceremonies and she said they still do offer them, but only for those who had driven 4 hours or so, not for locals. I thought it was a lame excuse, we were so few of us, I would dare to say only 6. But anyways, I was of course thankful and left the room.
 
**Important: I had done a Change Of Address at the time of my Naturalization Application, but it looks like they never got it. they still had my old address on file, thankfully I had brought with me the screenshot of when I changed my address through "My USCIS" and the confirmation letter they had sent me. She looked surprised. You have to go as confidente as you can!
***Important: She asked to drop off GC, Advanced Parole and Employment Card when taking the Oath. Do not forget!
 
Last update: Checked my account this morning and the N-400 says "Oath Ceremony Will Be Scheduled". Patiently waiting here. Almost there. 

There might be some details I left out that I currently don't remember? I apologize.
If any of you have any questions, please don't hesitate to go ahead and ask me.

Send a request for what is called a Service Motion.
They can re-open it using this - it is specifically within their powers to do so, so a letter and/or infopass clearly stating you didn't receive an RFE, so were unable to respond to it should eventually get it sorted...of course getting someone with an ounce of intelligence at USCIS to read the damn thing is not easy. 
It happens more than you think with RFE and interview notices.
 
The other option rather than waiting for a response to the above, is simply to file an I-751 again (and pay again) - with a letter specifically stating the late filing is due to the denial of the first filing in error.
 
 
And yes, before you ask, you can continue to work and remain a Lawful Permanent Resident until an immigration judge says otherwise (if you did nothing you would eventually get an NTA with a court date)
 

Sorry this happened to you, yes hire a good immgration lawyer right away.
 
You will likely need to file a new i751 before your case is sent to court for removal proceedings. There is no real appeal for an i751 case, not sure if you can get your old i751 reopened, somehow due to USCIS error or the post office mis handling the RFE notice letter.
 
In any case you should act quickly.

get a lawyer and take them to court. its a waste of time and resources with USCIS. Once the judge gets involved it makes life difficult for USCIS 

Thank you for the information, I will definitely look into that!!!

Finally done with the whole immigration process - I am now a US Citizen as of yesterday, March 22, 2021. Had my oath taking ceremony at the USCIS field office in Tampa, FL. Here is my timeline:
 
N-400
8/2/2020 - Submitted form and paid online
12/14/2020 - Biometric Reuse notice
1/4/2021 - Interview Notice
2/23/2021 - Interview Schedule
3/22/2021 - Oath Taking Ceremony
 
The ceremony was quick, and as mentioned by others before, no guests were allowed inside the ceremony hall. The whole affair lasted maybe 15-20 mins. Next up - updating my Social Security, applying for passport, and getting registered to vote!

You got a combo?! The exact same office told me they had "never heard of that being done before" in November when I had my N-400.  Four months later, and I'm still in limbo.
