Has anyone actually received an apostille from the Argentinian embassy? Because I have called at least five different apostille services in DC and they told me that because Argentina is part of the Hague Convention, they don't do apostilles and so it can only be done via the State Department.
I didn’t need to work with any US documents, but I'm pretty sure that you asked them for the wrong service and that's why they're not being responsive.
The entire point of the Hague convention is to
abolish legalization requirements. In fact, it’s literally in the name - the full name of the convention is the Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents.
If both Argentina and the US are signatories - and they are - that means you
do not need any Argentine consulate to legalize anything. The US legalization - when done in the manner duly prescribed by the convention - suffices to be accepted in Argentina.
The FBI report has to be apostilled
by the State Department. Full stop. Nothing else is required (except the translation, which has its own rules and really really should be done here).
Any apostille service in DC is there simply to expedite the process - to wit, to submit the documents
on your behalf to the State Department to be apostilled, and then to forward those documents to you. If you ask them to take your stuff to the Argentine consulate, of course they won't do that - that makes no sense.

slightly longer explainer earlier in the thread.
