They never asked her about it. She said that she didn't even get a chance to mention it since everything went by fairly quickly. Honestly, if everything's right in your application and you made a small mistake on the DS-260, I don't think it matters much. I suppose unless your situation is complicated to begin with, you have nothing to worry about! Just my experience though!
I taught to share this, if someone ask a question here, we should all bear in mind that they are in desperate need of vital info for their visa process, its best not to write anything you're not sure about so as to keep such people confused...why do I say this? During my time in AP, I had some people tell me its gonna be 1 to 3 years, I had some tell me its a denial and all sort of stuff..this got me so worried and had sleepnes night... Contrary to such claims, every approved visa undergoes AP before being finally issued..hence, my advice to not give wrong information when you know you're not sure of what you saying..there are people here who are well vested with the process and when a question is asked, pls lets kindly allow those who have specific and accurate info to advice... Hope this helps
