"John Jay's letter was about foreign influence."

Yes. It is.

"Dual citizenship allows for foreign influence."

So does going on vacation.

"Post an article based on records of the time that states that the Founders had no concerns with dual citizenship and foreign influence."

How's this? Thomas Jefferson was a dual citizen with France, becoming naturalized in France as an adult just before the Constitution was passed. The Framers did not seem to have any trouble voting for him as the third President in 1802. Not one of them even raised the issue.

"So Mr. Jefferson was naturalized in France and there made a French citizen, and had he gone there would have been entitled to all the rights there of an adopted citizen, but he certainly retained all his relations to the United States, his rights and duties as a native citizen, and was in fact after such naturalization, elected President of the United States."
