Does anyone know if a Canadian lawyer can formally represent someone in a US Waiver i-192 application via a G-28i form? I understand that a non-US lawyer "may represent parties in matters before DHS, provided that he or she represents persons only in matters outside the geographical confines of the United States," but it is unclear whether a US Waiver Application falls into this category and the US authorities have been most unhelpful.
Thanks, everyone!
