At what stage of the sponsorship are you two? Police check she'll have to go to consultoria juridica I'm sure, and the papers need to get certified by MINREX or the embassy won't accept them.
My wife just got called from the embassy asking for a new police record since the one we sent was "expired", tho the one we sent with the application was just the national one(for use in national territory only). Our process has taken just over a year since the time I sent the papers in because doing it on my own I made a mistake of sending the Schedule-A Background Declaration form without an actual hand signature of her. Let me know if you need any help.
