The Board of Immigration Appeals (Board) has determined that a non-citizen may give lay testimony about the psychological impact of his past experiences. The non-citizen does not need to be qualified as an expert witness to give this testimony. The Board also determined that when conduct by an Immigration Judge can be perceived as bullying or hostile, remand to a different Immigration Judge may be proper.
