Most of the "legal requirements" associated with MD-PhD programs are financing related. In general, such programs are usually sponsored and funded by national health ministries (or their equivalents). Therefore, it is preferred (or required) only to have legally qualified citizens participate in such programs. 

As for the choice of major, in general, computer science is not one of the usual entry points for MD-PhD programs, which tend to be more closely related to experimental programs and majors (e.g., chemistry, biochemistry, biology, bioengineering). That said, there is more of an emphasis nowadays on computational science in medicine, and more and more MD-PhD programs are expanding their scope to include bioinformatics and computational biology. But it is still definitely not a universal, and CS majors will be at something of a disadvantage. 

Prerequisities to become an MD-PhD?
I have very limited options in my kitchen, and while the dutch oven is the preferred method for getting an 'oven spring' while baking sourdough, I do not have a cast iron pot to do it.

IF stainless steel is a good substitute, should I consider extra precautions?
