Lots of info out there on the increasing # of US graduates with stagnant numbers of residency spots. End result: most likely harder for foreign grads to get any US residencies.
Financially, there’s risk of dumping money into a degree that won’t land you a US residency. I don’t think standard student loans from the US Gov can be used on foreign schools either, so could you assume all of the debt and all of the risk. The school says the program takes at LEAST 4 years, and some take longer. That means more family hardship and more cost. You should see what their graduation rate is, average USMLE scores, etc are. They don’t seem to advertise it on their page.
Academics: Online academics causes you to miss out on a lot of the collegiality of the classroom (know from experience). Med school is hard, and part of what helps you get through it is being around others who are suffering as much as you are… It’s probably possible, but in the US, you’ll gain a lot more clinical experience and motivation during the first two years with longitudinal classes that focus on medicine vs just pure basic science.
Family: There’s a good chance you’ll have to travel, a lot, for rotations. And those rotations may be limited in locations (ie not where you live now) based on where the school has affiliations. Plus, on their website, you’d have to do at least 1 rotation in Samoa.
There are things you’ll ultimately have to balance out based on you and your family. The general consensus is do whatever it takes to get into a US program before contemplating a foreign school (if you want to gain a US residency and practice in the states).
