Sort of but no "officer" needed to be "reminded".  I doubt there will be any noticeable change in how they exercise their judgement.  We'll see.

During the interview for B2 they usually even don't look at any documents only the form you filled out online which contains pretty basic questions. Moreover they get angry when people are too pushy and trying to show their connection to the country where they apply for visa.
They gonna ask questions about your trip to the USA and you have to be honest. That's it. 
Just apply and you will find out.

It's not required but it is very expensive to use medical services without insurance. 

As an example. When I just moved here I got in the minor car accident and I wasn't planing to do so) What I'm saying even if we are not planing to see doctors sometimes you just don't have any other choices. My leg was broken (nothing too serious) but I needed a surgery anyway, just a surgery alone cost $25 000.... Plus several doctor's appointments, x-rays and so on and so fourth. I meant it's a perfect situation if none of us needed to see a doctor but you never know.

USCIS has announced the new Public Charge Rule, it will become effective on February 24, 2020.
This Rule affects legal immigrants (those who are legally in the United States and those who are seeking admission to the United States) and illegal immigrants (who have never been eligible for the benefits covered by the Rule).
The Rule will apply to all applications and petitions postmarked on or after February 24, 2020. For applications and petitions sent by commercial courier, the postmark date is the date on the courier receipt.
USCIS will start to issue new forms that include public charge queries during the week of February 3, 2020.
“Old” forms submitted after February 24, 2020, will not be accepted and applicants and petitioners will be told to submit the “new” forms.
The Rule will not apply to benefits received prior to February 24, 2020.
The Rule does not apply in Illinois (at this point) where an injunction is still in place.
USCIS plans to issue guidance on the implementation of the Rule starting the week of February 3, 2020.

US  citizens are guaranteed entry.

I'm on the same boat. But it turned out that it's actually a good thing that we didn't send AOS last month cause when I rechecked everything over and over again I found some mistakes and I had time to correct them.
 
But I wouldn't wait too long because of new rules(

After months of preparation we finally sent our AOS package today via UPS. It should be delivered on Monday by 10.30 A.M. We decided to pay extra for faster delivery time because of new rules. You never know what's gonna happen next.

Great! We received our NOA1's in the mail yesterday  
The priority date on our I-485 is 01/22/2020.

You are very wise to submit it quickly anyway welcome to the thread and my your journey be swift. You are first here btw. And you are 100% correct you never know what might happen. I rushed to submit our packet in September because it was supposed to take effect that October 2019 before they put that hold on it now it's back. Again good move on your part.

I wanted to update everyone. I called USCIS on January 10, the help center told me that they've scheduled my interview but have not sent a mail yet. So I thought, he must be right knowing Los Angeles schedules interview 12-18 months. I was not worried with a wrong address because I changed my address back in October 2019, of which I received my EAD with the new address in Nov 2019. 
Well, last friday January 24, I found the mail I've been waiting for mailed to my old address in December 19. I live in the same building and I just changed apartment 3 floors up. The mail was left just above the mailbox so everyone can see. I opened the mail and I was scheduled for an interview today, January 29. I had medicals done last saturday and thankfully picked up the enveloped from the Dr. the day before the interview. 
 
So the interview went well. We were not separated. It was questions about how our relationship developed and names of our parents. I had a previous I140 petition back in 2006 which was also approved and he asked me about it. I gave him everything I could gather regarding joint accounts etc. He approved our petition right after we left. 
 
It was a busy last 4 days. I took time off from work to get all the paper work ready. Our lawyer wasn't even able to appear because it was too short notice.
 
I am just glad that this chapter is over for now. 
Thanks everyone who replied! 
 

Just a little note, not only Green Card holders can have A-Number. 

I got a RFIE for my affidavit of support, my husband and I filed joint tax return and he did not include his w2 with the tax transcript. We did send in his employment letter stating the hours worked and the hourly rate which is slightly above the proverty line, but immigration said he did not meet the requirements. I have a joint sponsor, USCIS is asking for his w2 for the joint tax return, should I also redo his form I864? Someone was telling me that I needed to do form I864a because it was a joint tax return, and I should put zero for my income, is it true? 
 

Our case fell under AWA
I retained a Lawyer he filed our K-129f we received NOA1 April 2019. July our petition was transferred to Vermont from California service center. Still waiting for NOA2  approval or RFE. 
Praying for all of us for Jesus to soften the consulars heart ❤️ for approval. Our attorney told me “he has seen my cases AWA get approved”.
