The summary is certainly useful, but all this is a bit more complicated. There are 27 member countries in the EU. The Swiss divide them in three groups.

• Group 1, also called EU-17 consists of the 15 countries that were members prior to the May 2004 enlargement + Malta and Cyprus

Your Q&A apply perfectly to EU-17.

• Group 2 (EU-8) contains the 8 other countries that joined in 2004.

For these countries, the answer to Q3 is different. Access to the market si restristed. The quotas are still applied, for example. Some other restricions exist as well.

• Group 3 is formed by Romania and Bulgaria, that joined this year.

Their nationals are treated as those of non-EU countries.
