I have made an address change online as well, and it didn't work for me either. I got the confirmation and all, but every single letter/package from USCIS was still sent to my old address. Even to this day, a year later, letters are still sent to my old address.

Send me your real name and I will forward to my contacts inside the USCIS.  The agency has special programs to aid scammers who don't know English to enable them to skip ahead in line in front of tax paying citizens.

Give us a break.  In the start of this post, you state it is your girlfriend.  In the previous thread you give the impression it is you.  Stop telling lies.  

We chose the K-1 because we thought it would be faster and because we didn't want to be separated after getting married. Turned out that the K-1 took much longer than expected.
 
If I had to do it all over again today I would go for the CR-1. The whole idea of not being separated after the wedding just wasn't worth the struggle with the K-1, the AOS and then the wait to even be able to work and drive and travel abroad on top of that. I'm obviously so grateful that me and my husband didn't have to be apart after the wedding, that we could start our life together immediately as married, not on opposite sides of the world. But yeah, I still wouldn't go the K-1+AOS route again.

My grandfather died while my mother was in Ireland.  She stayed there because it made zero sense to spend 3k on a round trip ticket for a funeral.  She was able to say good bye and watch the funeral via skype.  You may consider this inappropriate or heartless but I considering it using logic and common sense. 
My child lives in another country.  I purposely chose the CR1 visa so I could travel for an emergency.  We all make choices.  You have to live with yours. 

N/A is fine on the question about A-number. If the question wants you to answer with a number (Like "how many children do you have?" or questions of that kind) you answer "none" instead or simply just 0.
 
Even those of us who travel to the US on VWP get an i-94, you can check hers online. https://i94.cbp.dhs.gov/I94/
It's electronic nowadays so you don't receive a document anymore.

But OP isn't talking about the CR-1, they filed for the K-1. Believe it or not but there is actually a thing called "too married for a K-1 but not married enough for a CR-1". Which means that even if you didn't marry legally and there's no marriage certificate, you can still be denied the K-1 visa because of a "ceremony" that makes you "too married" in the eyes of the CO. 
 
If that happens you have no choice but to marry for real and file for a CR-1. For that you will need some sort of documented proof, what we call a marriage certificate, yes.

I did read it.  You obviously don't know the difference between "discriminatory" and "racist".

Those Mohammedans may be the ones affected mostly by the ban,  but the law itself isn't targeting Muslims.
Indonesia, the world's most populous Muslim majority country isn't targeted by the ban. 
Malaysia isn't in this ban, Pakistan isn't in this ban. UAE, Kuwait, Qatar, Jordan, Israel are not in this ban.
China which has 23 million Muslims, not in this ban.
Muslim from Canada, UK, Germany,France are not in this ban
As a matter fact, the absolute majority of Muslims are not subject to this ban
So, why are you calling this a Muslim ban?
 
Fake news isn''t cool.

It's still the "Travel ban 3.0" from Sept. 24th...just that SCOTUS allowed it to go into full effect yesterday.

The rules vary by country, but some (mostly those from the middle east) cannot issue any immigrant or non-immigrant visas. Others can only issue certain types of visas (i.e. student & exchange visas are allowed from Iran, but nothing else). One (Venezuela) only affects a very small number of individuals (government officials and their immediate family). The "bona fide relationship" exception on this order expired on Oct. 18th.
 
A waiver is available, but is only to be granted on a case by case basis (with no information on timelines or well-defined criteria for approval).
 
tldr: North Korea, Syria, Somolia, Iran, Chad, Yemen, and Libya nationals cannot be issued an immigrant (or K-1) visa. Further limits on other visas apply to a subset of those countries.

Saudi Arabia has nothing to do with the visa process, it's an American process and the interview will be held at the US embassy - where same sex marriage is perfectly fine. So marry in Canada if you want, but no reason to go through a visa process in Phi when you can do it in Saudi Arabia instead. 

Just because you earned enough the past three years doesn't mean you still do, that's why a letter from employer, paystubs etc are good to send. They might RFE you and ask for you to send them later on otherwise. 
 
With that said, we only sent in my husband's full tax return (not the transcript) for the latest tax year and only the 1040s for the second and third year and were approved just fine. However, he is self-employed so there are no letter from employer, W2s or pay stubs anyway in his case..

For a low fraud country these would all be non-issues. For a high-fraud country these might be potentional red flags. Where is she from and how big is the age gap between the two of you?
 
A 5 month long visit sounds good though, many get approved with way less than that.

Did USCIS actually receive your RFE response?

NO.  To file an I-129F for a spouse, you must file an I-130 first or at the same time.
