This is normal. Many people have the same problem. The estimate on MyProgress tab is not something you can trust or rely on. It shows inaccurate data and it has outages (disappears) from time to time. There's nothing to worry about. If you filed in June, you're under normal processing times. West Palm Beach shows 7.5 months for most of cases. I'd say February - March 2025 is when you'll get your case decided unless everything will slow down under new administration.
I presume you got two different I-485 applications - one for spouse and one for stepdaughter. I also presume you got two separate RFEs for each one of them. You need to send two separate RFE replies for each case. If joint sponsor's income is good to support both - great, otherwise you may need two different joint sponsors.
Which citizenship? LPRs are not US citizens, it would be a painful mistake to call yourself US citizen when only LPR.
CBP cannot revoke or demand to renounce any other foreign citizenships.
I do not have compelling evidence that K3 speed up anything. Neither lawyer and others who observed immigration for years. It simply doesn't make sense that USCIS is going to drop everything and process somebody faster just because a free form was filed for them. It's not in manuals, it's not in policies. And there's no proven record of it. Some cases get approved super fast without K-3s, expedites or anything special. Some just get lucky.
The normal is an average. Actual cases can take few months less or few months more. K3 is an urban myth. If anything, it takes away time USCIS could use to adjudicate more I-130 instead of opening K3 packet and and putting it in trash can.
MyProgress tab is very unreliable. Neither estimates nor current steps can be trusted.
Just keep checking online account and wait for physical interview letter.
Possible, but then they're violating the law flying over residential areas at night.
Looks like two amateurs got arrested, probably too curious. I hope it's just US government conducting some tests. Hopefully, we'll learn sometime.
That's my impression based on OP's messages so far. E.g. they didn't get vaccinations required when doing DS-3025
And/or is the focal point of this thread as far as I understand. Most civil surgeons don't honor or. They either do whole medical with vaccinations or turn people away.
