I have no DNI. Wife is not a us citizen. Child is US and Argentinian citizen. I have no DNI un Argentina. We were in Lima on vacation when Peru suddenly shut everything down.
And your wife does not have a Green Card? So returning to the US is not an option? Do I understand that you cannot return to Argentina because flights are only for stranded Argentina citizens? If this is all true, you will have to wait until normal flights resume. I don't think it will be years but I think it could be a few months. If you can get to the US to sit it out, all the better. Have you spoken to an officer in the US embassy?
