I don't see a reason for any other types of letters from the bank to be rejected. E.g. letters with alerts, updates, promotions. Did you have negative experience with this?
On the day of marriage or after? I don't know how it works in Utah, but in my city I:
1) Got marriage license weeks prior to ceremony
2) Got memorable marriage certificate on day of marriage
3) Applied and got legal marriage certificate few days / weeks later.
So for actual certificate, I had to apply for it and wait. Was this the case in your situation?
That's a good point.
I expect though, USCIS expects certificate similar to what @Elavod posted.
To me RFE is clear, they expect document A and OP provided document B.

This is pretty normal. Typically civil surgeon will perform a new exam instead of completing form started by other civil surgeon.
This subject keeps popping on VJ all the time, yet nobody seems to take it seriously...
As @Boiler mentioned, best time to get exam completed is overseas.
Sure, it can be asked by USCIS / other agencies at certain points in the process. It also proves you have a case. I would start worrying if it doesn't show up 8-10 weeks from filling.
No, this is not a receipt notice.
Receipt notice will be printed on greenish watermarked paper.
Does this have case number? It's possible you can access your case online before other letter arrives.
Sometimes mails go different routes and USPS delivers one before the other, even USCIS sent them together.
Are you a sponsor or beneficiary?
I-130 is for US citizen sponsor
I-485 is for immigrant who's adjusting
Therefore they are different accounts for two different people.
Wait time of up to 8-10 weeks is what is expected nowadays.
Did you file G-1145 with I-751? If yes, you have 50% chance you'll get email / text message when case is created. Otherwise would have to wait until you receive mail. Then you'll be able to add case to MyUSCIS.
You can check case status then in MyUSCIS OR (probably more reliable solution) here: https://egov.uscis.gov/
The reason it's more reliable it doesn't require logging in, and historically it worked many times when cases temporarily dissappeared from MyUSCIS or it gave some error.

Notice the accuracy of these estimates. Imagine if weather forecast said "It's going to be sunny 85F tomorrow" and in an hour changed to "It's going to snow tomorrow, highest temperature 20F". How accurate this forecast would be?
This estimate is not accurate. If you read VJ threads you'll see people reporting this estimate changing all the time.
How long is the trip? If it's few weeks and you can monitor USCIS case status and USPS Informed Delivery plus return home if scheduled for interview - I see no issue.
That's smart as you can only file N-600 once. Is N-600 needed to get a job / sponsor somebody for immigration benefit or you're getting it as "insurance policy"? If the latter, then it's best to get all info required even if it takes longer.
