Unfortunately, you will need to attend Podiatry school in the US to be eligible for Podiatric Surgical residency program in the US. With your MBBS degree, you will be able to enter Podiatry school with advanced standing (meaning that they will give you credit for the basic science courses and you will not need to attend 4 years of Podiatry school to get the DPM degree). The advanced standing will vary with each Podiatry school. Once you are in the last year of Podiatry school and you have passed the necessary APMLE board exams, you will be able to apply for the various Podiatric Surgery residency programs. The residency programs are 3 years in length (with a few programs 4 years in length). Some people also pursue fellowships after finishing their residency training and before heading into practice.
