That would depend on where you are from. Different countries have different rules and arrangements with other countries.
For some European countries they would need a visa.
When you say visa; are you planning on working, going to school, or something similar? If not, you do not need a visa. Also, you do not need a visa if you are just going to Europe for a visit. But you will need a visa if you are planning on moving there or staying for a certain length of time.
Answer one:There is not a single Europe visa. Europe has many countries and it will depend on where you are coming from and which countries you are going to as to what visas you will need.Answer two:If you are coming from the United States you do not need a travel visa to visit Europe. I was there earlier this year--you can travel from Sweden to Italy and cross from Lithuania to Finland without ever showing even your passport.In fact, I tried to get Swedish customs officials to stamp my passport just to collect the stamp. They replied, "that is so old fashioned. We do not do that anymore."If you plan on staying in a country for a length of time, you will need a visa for that particular country. Consult your embassy for information on that.
No, they are European citizens.

UK visas and Schengen visas are nothing to do with each other. Whether you need a Schengen visa or not is decided on by your nationality.
If you are a Finnish national then you do not need a visa to travel to the United Kingdom. Both Finland and the UK are members of the European Union in which there is a free travel agreement. Citizens of any EU member state can travel visa-free to any other EU member state.
If your travelling from the U.K. then you don't need a passport but some form of I.D. is reccommended. If your from Europe then you need a passport to get into Ireland. Outside of Europe then i think you need to apply for a visa and bring your passport.
Finland is an independent country on the continent of Europe.

If you have a Schengen Visa, you do not need a Visa to enter Switzerland. But, just make sure that you have this written "Schengen Estate" on the visa. It means that all Schengen countries are included in the visa. Anyway, once you enter Europe, nobody asks you about your visa or passport.
