In addition to DM and DNB the Medical Council of India has recognised the degrees granted
by six english speaking nations – USA, UK, Canada, Australia and New Zealand. For each of
these countries there is a legitimate degree granting authority. These authorities have an
online system that allows you to verify if the doctor indeed has obtained the degree he or
she claims to have obtained. For e.g., the american board of internal medicine is the
authority for those who have obtained their training in the US and it has has a verifying
system here.
