Need to get our Constancia Fiscal from one of the SAT offices in GDL. Has anyone had personal experience with either location, recently? If so, can you please share your recommendation? I have the documents needed and will call for an appointment, was hoping to hear from someone who's been there to accomplish this task before calling the office that may be most efficient. I understand that once there, the process only takes about 15 minutes. Thanks in advance. Salud! Val Jones :)
