Several European countries appear year after year in various ratings of countries with the best medical care. Of course, regular inclusion in the various “tops” is not a coincidence, but a regularity due to the high quality of services.
According to the World Health Organization, among European countries France and Italy are leaders in efficiency and accessibility of health care. It is extremely difficult to obtain a French or Italian passport (or even residence permit status) entitling one to treatment at a reduced cost due to strict quotas.
However, these states widely practice medical tourism, providing high-class services to citizens of other EU countries. And from this point of view, in order to be treated in France, it is not necessary to obtain any official status in this country. It is enough to have a residence permit or citizenship of the European country, which provides favorable conditions for its receipt.
You can issue a residence permit or even a second citizenship in Hungary, Greece, Portugal, and a course of treatment in French or Italian clinics. This is much easier and more profitable than resorting to medical tourism, coming for treatment from Russia.
However, the most profitable treatment will be if you get official status in the country where you are going to use medical services.
