In this context, 'foreign agent' means 'agent of a foreign power', not that one is a foreigner. This is what US Senator Bob Menendez is being prosecuted for; it's alleged that he was an undeclared agent of the Egyptian government. AIPAC is run by Americans, but it does advocate on behalf of the state of Israel; I'm unclear to what extent it is financially supported or directed by the government of Israel. Having IDF people advising on information war strategies (as described in the article) does make it seem official though.
