What are common reasons for a 221g "inaccurate information?"

[CM&KV 72]

I'm unsure if I'm posting in the right sub forums, please move this to the right one if this happens to not be it.

I know each case is different, but I am trying to find the common reasons why someone would get a 221g with "contains inaccurate information."

I assume the beneficiary not knowing the information in the packet. But what if they know everything in the packet but the CO made up their mind before hand? I read some threads about the CO barely asking for documents and asking questions and they were given a 221g with "inaccurate information." And they don't know the full reason behind it.

One that I just got done reading was about someone's ex-wife was filing for a k1 at the same time, both of them were the beneficiary. The couple only knew this because of their 2^nd k1 interview, which they got approved. I only found this because I looked at someone’s past postings.

I'm having a hard time finding any answers, and google search is not being helpful, unless I'm inputting the wrong words.

I have no pending petitions at this time, but I'm afraid that my info might trigger this 221g.

exact, each process is unique, take the relationship of evidence you have, go quiet, if you have problems, a true relationship can show. it would be interesting you create a timeline, so other users can have access to your information in the process. (Sorry for the mistakes, I'm still using Google Translate) good luck and peace

I would be filing for a k1 or spouse visa in the late winter or early spring of 2017. If I had something pending I would have had a timeline filled, and yes it has become a pet peeve that people don't fill them out.
