With offshore schools the rate limiting step has changed from acceptance to med school to the match.
Almost anyone with a valid MCAT score and a diploma can get into
some Caribbean school, but getting into one of the better ones (SGU, Ross etc.) is similar in stats to a low tier osteopathic program. However, it is still generally easier to get into a better Carib school because most of the low tier osteo programs have lower stats due to regional bias and selectivity for their mission.
The middle to upper tier osteo programs are significantly more difficult to get into as they have 3.5-3.7 and 26-29 averages with mission and fit selectivity as well. They also match at 90+% and have a lot of opportunity match into almost any specialty (some limitations on program) with a solid showing in grades, rotations, and boards. This is clearly not the case for Carib school grads (other than the ~1% of anecdotal cases).
Regardless, I wish you the best and hope you are able to match
