Yes sure! He should know, the Cartilla del servicio militar is a document required just for men, they have to get that document by doing social sevice for the army in Mexico when they turn 18 years old. Did he never get it? It would be so strange, because as far as I know it is also a requirment for the passport too (I'm women I'm not sure)...
He said he didn't get it because he wasn't in Mexico at that time (studying abroad) and now he doesn't know how to get it. He is back in Mexico now. Any idea what government agency to ask about this?
