Based upon the information provided your husband would need to answer "yes" as he was confined to a mental institution in the past. His confinement in a mental institution will not result in an automatic denial of his application for naturalization, but it will make the case more difficult. Your husband will need to obtain records related to his confinement. It will need to be established that your husband is not a danger to himself or others. He will also need to establish he is competent to understand the oath. I encourage you to at least consult an attorney before filing.
