Any attorney who is a member in good standing of the bar of any court of the United States or of the highest court of any state may appear and practice before this court in that action at the court's discretion and on motion by a member of the bar of this court who is actively associated with him or her in a particular action.  The court may at any time revoke such permission for good cause without a hearing.  An attorney so permitted to practice before this court in a particular action shall at all times remain associated  in the action with a member of the bar of this court upon whom all process, notices, and other papers shall be served, who shall sign all filings submitted to the court and whose attendance is required at all proceedings, unless excused by the court.

An attorney for the United States who is not eligible for admission under subsection (a) of this rule may apply for admission under this subsection.
