I am a U.S. citizen with permanent residency (rentista) in Argentina. I recently got married in the U.S. to an Argentine national. I am not interested in Argentine citizenship, and I already have residency, so is there any reason that we would want to inform the Argentine government that we are married? We informed the U.S, govt so he could get a green card, but we aren't planning to say anything to the Argentines. Would there be any benefit to registering here? If so, how would we do that? Thanks
