Traditionally, it is not used to being a pathway sought by foreign nationals. 29 states have gazillion languages and its not always easy to communicate. Also may due to cultural differences, work hours and pay have also dampened its allure. So its not a path travelled often. But there are provisions! According to MCI',Provided that in the case of a foreign national, the Medical Council of India may, on payment of the prescribed fee for registration, grant temporary Registration for the duration of the postgraduate training restricted to the medical college/institution to which he is admitted for the time being exclusively for postgraduate studies; Provided further that temporary registration to such foreign national shall be subject to the condition 5that such person is duly registered as medical practitioner in his own country from which he has obtained his basic medical qualification and that his degree is recognised by the corresponding Medical Council or concerned authority'

Institutions like AIIMS and JIPMER have residency seats called postgraduate MD/MS reserved for foreign nationals. All of us have an entrance exam in June and November usually, and allotments are twice an year.
Over the last couple of years, especially service oriented doctors are inclined to try the Indian medical practice. So there is a change in trend with foreign degrees being recognized and check out this article on that

Now our honest situation after medical school, we have an intern year and then we register. There are almost hundred thousand doctors here with no residency spots. Each year only a mere thousand out of this pool, ie less than 10% make it. After graduation, we all take a gap year to write an entrance test and like I said most of us don't make the cut. Its not a hard test but every half point your rank goes down a few thousand. I'm hoping you get a picture. To top that, we have a reservation system for underprevileged communities. So afterall that, we never really have many positions. But in jipmer and aiims, in the entrance, foreign candidates have desperate reserved seats.
