why do you want to do that? residency training oversea is not recognized in US. that's the reason why IMGs have to do the residency in this country to be eligible for the license, no matter how much training they got from abroad. I know you can do one month rotation during your residency. if this is what you mean, you should have no problem to find a short term rotation in the countries you mentioned. Talk to the residency program in the US, ask for the international rotation requirement, but bear in mind foreign medical training is basically for your personal experience, not for the credit to practice some specialties in US.
