Being an attorney doesn't change the fact that the only legal notary outside the US is the consulate. All attorneys are notaries.
You can use a foreign notary but then you need it approved in the US and jump through some other hoops, or the simple way, use the consulate.
"Notarizing officers at any United States Embassy or Consulate abroad can provide notarial services similar to the functions of a notary public in the United States. It is also possible to have a document notarized by a local foreign notary and then have the document authenticated for use in the United States. In countries that are party to the Hague Apostille Convention, this is a simplified process that does not involve Embassies or Consulates. See the Hague Conference website for complete information on the Apostille process."
