Hello!

When someone need a medical service

And come out from a airplane

And have later a connection flight to fly home , but need medical service , but not have any visa that would allowed to enter a country, is there any law, that some country's make a excuse . And allowed to enter a country with out visa for medical treatment of a person needs it?

In what country would this "emergency" take place ?

What is the nationality of the person who has this "emergency" ?

Sorry, but we will need a little more information before we can comment

One would like to think "yes", but would depends by the country and circumstances I imagine.

all countries have procedures in place for medical emergencies, visa status is not an issue during the emergency situation.

However definitions of "emergency" will vary. If this were allowed too easily, some people would simply claim illness in order to enter a country in which they were unable to get a visa. Most likely if the airport has a doctor on call s/he would have to verify the level of urgency. If you were visibly ill when you started the first flight the airline would probably not allow you to board.

... and they'll give you the bill when you're better then escort you to the airport and wave you goodbye.
