28 U.S.C. § 1391 : US Code - Section 1391: Venue generally

      (a) Applicability of Section. - Except as otherwise provided by
    law - 
        (1) this section shall govern the venue of all civil actions
      brought in district courts of the United States; and
        (2) the proper venue for a civil action shall be determined
      without regard to whether the action is local or transitory in
      nature.

      (b) Venue in General. - A civil action may be brought in - 
        (1) a judicial district in which any defendant resides, if all
      defendants are residents of the State in which the district is
      located;
        (2) a judicial district in which a substantial part of the
      events or omissions giving rise to the claim occurred, or a
      substantial part of property that is the subject of the action is
      situated; or
        (3) if there is no district in which an action may otherwise be
      brought as provided in this section, any judicial district in
      which any defendant is subject to the court's personal
      jurisdiction with respect to such action.

      (c) Residency. - For all venue purposes - 
        (1) a natural person, including an alien lawfully admitted for
      permanent residence in the United States, shall be deemed to
      reside in the judicial district in which that person is
      domiciled;
        (2) an entity with the capacity to sue and be sued in its
      common name under applicable law, whether or not incorporated,
      shall be deemed to reside, if a defendant, in any judicial
      district in which such defendant is subject to the court's
      personal jurisdiction with respect to the civil action in
      question and, if a plaintiff, only in the judicial district in
      which it maintains its principal place of business; and
        (3) a defendant not resident in the United States may be sued
      in any judicial district, and the joinder of such a defendant
      shall be disregarded in determining where the action may be
      brought with respect to other defendants.

      (d) Residency of Corporations in States With Multiple Districts. -
     For purposes of venue under this chapter, in a State which has
    more than one judicial district and in which a defendant that is a
    corporation is subject to personal jurisdiction at the time an
    action is commenced, such corporation shall be deemed to reside in
    any district in that State within which its contacts would be
    sufficient to subject it to personal jurisdiction if that district
    were a separate State, and, if there is no such district, the
    corporation shall be deemed to reside in the district within which
    it has the most significant contacts.
      (e) Actions Where Defendant Is Officer or Employee of the United
    States. - 
        (1) In general. - A civil action in which a defendant is an
      officer or employee of the United States or any agency thereof
      acting in his official capacity or under color of legal
      authority, or an agency of the United States, or the United
      States, may, except as otherwise provided by law, be brought in
      any judicial district in which (A) a defendant in the action
      resides, (B) a substantial part of the events or omissions giving
      rise to the claim occurred, or a substantial part of property
      that is the subject of the action is situated, or (C) the
      plaintiff resides if no real property is involved in the action.
      Additional persons may be joined as parties to any such action in
      accordance with the Federal Rules of Civil Procedure and with
      such other venue requirements as would be applicable if the
      United States or one of its officers, employees, or agencies were
      not a party.
        (2) Service. - The summons and complaint in such an action
      shall be served as provided by the Federal Rules of Civil
      Procedure except that the delivery of the summons and complaint

      certified mail beyond the territorial limits of the district in
      which the action is brought.
