> What country lets non-citizens just walk in to use the health care system? Almost all. Non citizens just pay a fee or are reinbursed later by their insurance or healthcare system. In many cases citizens from country 'A' can use healthcare in 'B' as long as their own citizens will be granted the same treatment in exchange when visiting 'A'. It depends on the treatises signed between the two countries. Allowing foreigners to use the health care system for free is sometimes allowed (or even encouraged) if that protects the interests of the country.
