I think everyone kind of missed the OP's question. I believe he was wondering if going to a DO school in August of 2010 (like, next fall, 10 months) or starting MD school in the Carib in two months had a significant grounds for reconsideration.
This is a tough one, and I agree that its nice to have admissions in three rolling dates at carib schools - while most MD/DO schools start up in August each year. If you are not waiting on any other potential acceptances, or MD schools this cycle, you may as well just head to the Carib school and get this started.
I think the theme among every doctor, resident, fellow has been to get the ball rolling, start and get into the process. Everyone can linger around for years doing their MCAT, EC's and applications but it wont matter in the long run. If you had to go Carib, thats the dregs but a ton of people have and they need to know their own capabilities.
I also am completely mind boggled at the opinion - 'US trained' when considering the DO schools. I believe all students at Ross/SGU complete 18 months of basic sciences and pack themselves up for a two year set of rotations in affiliated hospitals in the USA. I have no idea where this myth perpetuated that Carib equals foreign trained doctors. No. Just no, wrong, ignorant.
These students are training alongside MD and DO 3rd/4th year students in the US of A. They also attend residencies alongside them, and live, breathe and practice alongside one another. 1/3 or more of doctors in the US are foreign trained, which isnt even a bad thing, but don't blow this out of the water and say going to a Carib school means they are training in the sticks.
