§  223-b. Initial entry by out-of-state banks by de novo branching. In  addition to the authority of an out-of-state bank to maintain  a  branch  or branches by means of an acquisition transaction, an out-of-state bank  may  enter New York by establishing one or more de novo branches in this  state; provided,  however,  that  in  each  instance  the  laws  of  the  jurisdiction  where  the  out-of-state  bank  has  its  principal office  expressly authorize a New York bank to establish one  or  more  de  novo  branches under conditions no more restrictive than those imposed by this  section as so determined by the superintendent.
