My husband and I have been married since 2005 and we are still married. He is communicating well most of the time but when I tell him I want to be a citizen like him and my daughter, he thinks it is not necessary for me now and he doesn't want to give me his citizen date and place information to write on the form. I am not filling it because of being a citizen spouse, I am filling it because of being here more than 5 years. I wrote unknown for his two information. Do you think I should put an explanation letter or just write unknown and if they ask, Then explain it with a letter or at the interview. I don't want my application to be rejected so that is why I am asking about that. There is not an instruction to put an explanation letter on that part but I was just thinking in case.
