Nursing study in Europe

Interesting question, and I'll be interested in the answer! You would not be able to work in the United States....but Europe? Someone here will know :)

Well IELTS would be useless if you wanted to work in most of Europe that does not have English as its primary language (France, Germany, Italy, etc). So that sounds like a random extrapolation. UK mandates IELTS for immigration & visa for all entrants even if from an English speaking country.

UK does not participate. And nearly every country listed does not have English as their primary language.

It does not appear this visa applies to nurses particularly. Not all countries offer nursing degrees (some are diploma only) nor do they offer masters degrees.

You would need to demonstrate linguistic proficiency in the country you wish to work whether Polish, Czech, German, French, Norwegian, etc.

So with schengan visa how long I can work Ther after studies

I think you are oversimplifying. Which country? Are you fluent in the language and medical terminology of the language? Length of visa depends on work contract obtained and qualifying by the country standards and proving language competency.

It seems the length varies from 90 days to several years if you obtain an approved work contract for the longer duration. It appears simply studying in the country does not automatically qualify you. What country do you wish to study, live & work in? Not all European countries even recognize BS or MS level nursing. Germany, Bulgaria, Belgium and Romania are countries that do not have MS as a level of education. Romania refers to nursing nurses as medical assistants.
