Thanks for the reply,
I was hoping to get some recommendations for some safety schools that have a good Latin American History PhD program (Modern History). Ideally, I would like to be accepted into a university such as Columbia, but it is probably wise to have a plan B. I have found it rather difficult finding good programs since most schools, and even some of the big names, focus primarily on Mexico and Brazil, but less on the rest of the region. I rather skip the M.A. since I already did a masters in another field and I am quite sure regarding what I want to study.
