you have a red flag because of your paperwork.. i highly doubt that the io will ask you " is your wife /husband here? ooooh, sorry i can't approve this.. " see how crazy that sounds.. also your wife/husband can't do anything anymore right there because the problem to begin with is your paperwork not her/his lack of presence.. having her/him there will not change anything if you paperwork is amiss.. you think the io will say" yeeeah, you paper work is not quite right but hey, since your husband/ wife is here, congratulations fellow citizen"..

How are you measuring speed? Fast is just a verb to describe the object. The entire process invovles some level of correct legal subjective process.
Fast doesn't means it will be legal and correct.

13 month battle in the AOS only to get a two year conditional card, spent the next 21 months gathering evidence for that. Only to get a one year extension notice that also expired requiring a 450 mile trip to get an I-551 stamp. A day wouldn't go by with thoughts about the USCIS ruling our lives.
Because of frustration with the USCIS, elected with a long talk with my wife to apply for citizenship at the earliest date, only way to get freedom. Another factor from experience, having a loved one hit by a hit and run driver, then getting expelled from my health insurance policy with a precondition where after all of your reserves are ate up and public assistance is the only option. No way with that I-864 hanging over your head.
Yet another problem was with my wife's employer since our state passed a law for hiring an illegal with a $16,400.00 fine, their legal department was driving us nuts with an expired green card and that crazy one year extension. Then also problems with our DMV refusing to renew her drivers' license, what the hell is a one year extension?
We sure needed a break after that AOS and ROC go around when her ten year card finally came in, but elected to apply for citizenship at the earliest possible date. This meant copying another inch thick of documents, reading all the rules, trying to make heads or tails out of that sloppy N-400 form written by the then current director that can't even speak English let alone write it.
We thought on advantage of going through this marriage BS would be free from her consulate with a US passport, but learned the hard way our DOS made an agreement with the country she was born in and not even lived at required her to maintain her foreign passport. That was a negative, but at least we were finally free of the USCIS, that was worth the effort. I think we have a law now where preconditions in health insurance are no longer a burden, but still is great to be free from that I-864 and having to inform the USCIS we are moving across the street.
And once my wife showed her legal department her certificate, closed that file on her, no longer asked, where is your green card. She also feels she is a part of this country. Also took me awhile not to think about collecting evidence, keeping records on our travel, employment, and address changes.

if she has not file form i130 then an info pass is needed ASAP to determine what needs to be done. Else down the road, she may be in trouble
