Right?! And the part that's confusing me is they don't necessarily say that the Police Certificate is expired. They only say they need the "Contrato exclusivo para la obtención y legalizatión de CERTIFICACIÓN DE ANTECEDENTES PENALES, issued by the Consultoria Juridica Internacional".
But later in the letter it says to send both this and the Police Certificate together (I had no idea we needed two documents). They have the original Police Certificate, dated Oct 31, 2018. Would this also mean they need an updated Police Certificate as well?
Going to try emailing Mexico, and see what they say.
