~ Moved from K-1 Process to AOS from Family Based- OP on that path now ~
Translations can be done by anyone fluent in both languages> http://www.visajourney.com/content/translations
You only need to translate any of the documents required for AOS that are not in English, such as the foreign spouse's birth certificate.

Russia and Ukraine are different in how they treat multiple citizenships, so talking about one doesn't really mean something about the other. (China is also different, in case the mod who closed the original thread is still confused.) It's true that a Russian citizen can gain citizenship in another country (at least in the US, in particular) without losing claim to Russian citizenship. However, a citizen of another country who wishes to gain Russian citizenship is required to renounce their former citizenship. In particular, you must write a letter to your consulate stating you wish to forfeit your citizenship. The actual effect that this will have varies depending on what the second country is. The US, for instance, requires that you renounce citizenship in person and thus a letter to that effect doesn't have legal force. An individual born in the US to at least one Russian parent (or an individual born in Russia to one US parent and one Russian parent) has a birthright claim to both Russian and US citizenship. Filing at the appropriate consulate or embassy would be required to obtain documentation to prove the second citizenship. The individual is not required to give up either of these citizenships at any time.
However, neither the US nor Russia allows dual citizenship. They allow multiple citizenships. Both countries treat you as either a citizen or not a citizen. If you have US citizenship, you are a US citizen. If you don't, you aren't. In neither case does it matter if you have Russian citizenship. The same is true of Russian citizenship.
As far as Russia and the US (but probably not Ukraine or China), the only time you would do something illegal is if you tried to use a foreign passport to enter the country that you are a citizen of. That is, if you are a US citizen, it is illegal to try to enter the US with a Russian passport. If you are a Russian, it is illegal to try to enter Russia with a US passport. In certain similar situations, it might be illegal to use a foreign passport when you have a domestic passport. Basically, while in Russia, you are Russian. Trying to use the US passport is illegal because you are basically denying being Russian when in fact you are. The same applies to trying to use the Russian passport in the US.
An individual with both Russian and US citizenship should use the Russian passport for entering and leaving Russia and the US passport for entering and leaving the US. Typically you will have to show your foreign passport to the airline worker to prove that you have documentation to enter the country to which you are flying. At least as far as Russia and the US, you wouldn't want to enter Russia with the Russian passport and leave with the US passport. For one thing, the stamps won't match up and for another you'll have trouble leaving with the US passport since it doesn't have a visa. I can see why that might work in Ukraine, but it's probably illegal.
On a side note, you can't legally apply for a Russian visa in the US passport or a US visa in the Russian passport since you shouldn't need a visa to enter the country you are a citizen of. This may raise the question why you would want to. Basically, it can come up if one of the passports has expired. Say you have been in the US for an extended period and the Russian passport has expired. The simplest course of action might be to get a Russian visa in the US passport, instead of renewing the Russian passport. However, since you are entitled to a Russian passport, applying for a visa is illegal.

I can only comment on Houston - it did seem a little quicker than previous two international flights I took earlier this year into Houston...
The line kept moving - didn't really stop from what I can remember.
This was around 5pm on a Sunday - which going by the records/history on CBP site, is a peak time for Houston (IAH)
That's why I picked Monday for my wife's POE
See https://help.cbp.gov/app/answers/detail/a_id/1695/~/i-94-automation---will-cbp-still-issue-paper-i-94%3F for further info regarding the electronic processing.
It is only for air/sea travelers, where they can leverage the advanced info they request and scanning your passport also.
Apparently you can still get a I-94 later - from a specific website listed on the page below:
http://cbp.gov/xp/cgov/travel/id_visa/i-94_instructions/i94_rollout.xml
Good luck to all who POE - as I will tell my wife (I will be there with her for as far as they let me) - smile, say good afternoon and be confident - all else will be good.

Can't speak for Uganda, but here in Russia I didn't get no "packages".
After NOA2 (Apr08) the letter was sent (Apr24) to the Petitioner that the case has been received by NVC and will be forwarded to the respective Consulate within a week. It also stated that the fiancé (me) will soon receive a packet with instruction on how to file a K1.
Later (May08) the Petitioner (again not me, the foreign fiancé) received this
"

I wrote the email inquiry (May07) about my case to the Moscow Embassy at the same time. I was under the impression I would get an actual package. Instead the letter with approximately the same content was sent to me (May14):

So...no physical package with instructions. I called Embassy phone line and they said I won't be getting anything, but this letter. I can schedule interview and collect documents. So in case with Moscow Embassy they didn't physically mail me anything prior to interview, and I didn't send them anything either. Hope this answers your question.

Says you need an English translation for the birth certificate and police certificate.
Russia seems to be an exception to the general rule of "you don't need to have translations of things that are in the native language of the country" that most other consulates follow. Even here on top it says you only need to have translations of documents that are not in English or Russian, but then goes on to say that you do need translations of the birth certificate and the police report.
