I am asking question on behalf of my mom as today she was denied citizenship because she did not pass (according to USCIS officer) understanding english test. During her first try (few month ago) she passed writing and reading test but she could not clear the understanding english test. The interviewer allowed me to sit in the interview to so he told me to explain my mom that she will get second chance and asked us to study only questions from part 13 of N400 form. During that time she lost her brother (my maternal uncle) and so she had to reschedule the interview. So fast forward today was her second chance and this time it was new interviewing officer. She asked my mom lot of personal questions pertaining to my maternal uncles death and my mom is not a good in english and she barely prepared the part 13 of N 400. But when she was questioned over and over her brothers death she started crying reminding of her brother and interviewer said that she cannot grant her citizenship as she does not understand english very well. When i was called inside i was explained by the new interviewer what happened and i gave her the name of previous interviewer from same office saying that he asked my mom to prepare only part 13 of N 400. At this, the interviewer got offended and said that i am trying to teach her how to interview her mom and she cannot do that. So i tried to explain her that there is clearly miscommunication as the first interviewer asked us to prepare only part 13 of N 400 and yet she went on and on asking my mom about her brothers death (kind of personal). So i requested to speak with supervisor explaining him about the harsh decision that was made without even questioning my mom any interview related questions. At this, the supervisor said that only option i have is to appeal and i can write a cover letter of what happened but the decision cannot be reversed. I want to know what are our chances to win this appeal ? If we win the appeal, does my mom get another chances to be re-interviewed ? I would sincerely appreciate if someone can provide me with some advice.
