The flt. schools that I am familiar with in C/S America (Guatemala and Colombia) actually have higher standards than what I am familiar with in N. America and Europe. They put an emphisis on actual flying skills. Similar to how flt. schools in the U.S. and Canada used to be (not all schools of course).
As PJ says though, flt instruction in this region will be very expensive. And, your chances of finding any flying jobs In this region once you have attained your ratings are very remote.
