Personal jurisdiction over foreign defendants in state courts is limited by state statutes and by the Due Process Clause of the Fourteenth Amendment of the U.S. Constitution, which the Supreme Court has interpreted to require that defendants have “minimum contacts” with the forum state. Personal jurisdiction in federal courts extends in most cases only as far as the jurisdiction of the state courts of the state in which they sit.

Personal jurisdiction in federal courts is limited by the Fifth Amendment’s Due Process Clause. The analysis of personal jurisdiction under the Fifth Amendment is more flexible than the "minimum contacts" analysis under the Fourteenth Amendment.
