Why would a Settlor want a non-U.S. protector (or professional protector)?
If the Settlor is a United States resident, the U.S. courts still have jurisdictional authority over that person. Although no case law exists on the subject, theoretically the Court could force the U.S. protector to appoint a new Trustee one who works for the U.S. Court. This is just theoretical, but many clients prefer to remove any doubt of jurisdiction of any kind and will therefore use a non-U.S. protector. These non-U.S. protectors are typically professional Trustees in a jurisdiction other than the situs of the Trust (in a country where the Trust was not settled).
