I stayed in Paraguay for 6 weeks in 2011, and I'm going back in a few weeks. I have a multiple entry visa (which expires Dec. 2014), but it's in my old passport. Technically, my old passport expires Dec. 23, 2014, but I have a new passport that I recently got a few months ago. I'm flying through the airport from EZE in Buenos Aires to Asuncion. Does anyone know if customs will accept my visa in my old passport?
