1. Does AIPAC's use of dual-citizens (American-Israelis) allow it to circumvent the Foreign Agent Registration Act?
2. Is there any other analog to AIPAC operating in the United States for a foreign nation?
2. Five China news agencies and Russia Today are registered as foreign agents. There are also over 200 foreign PACs, but they're mostly businesses. The Overseas Friends of the BJP (the ruling party in India) is registered as a foreign agent. That's probably the closest match.
From Wiki: 'FARA requires those who receive funds or act on behalf of a foreign government to register as a foreign agent. However, AIPAC states that the organization is a registered American lobbying group, funded by private donations, and maintains it receives "no financial assistance" from Israel or any other foreign group'
