There are several benefits for joining the European Union including membership into the largest single market, access to foreign direct investment and the citizens' right to relocate anywhere within the European Union without a visa.
The benefits of joining the European Union are expansive. The largest single market is very attractive because it bears a GDP of £11 trillion. Moreover, the European Union regulates trade with one set of regulations, which makes business much more efficient. Additionally, the European Union is working hard on eliminating high export tariffs to further increase the prosperity for each member state.
Countries that join the European Union provide invaluable benefits to their populations, too. Citizens can move for work, school or desire without having to secure travel documents. EU members can stay in another EU country for up to three months without having to register with the host country.
Citizens do not have to apply for a driving license for every country with the introduction of the European drivers license. This license follows common driving standards and is valid in every EU nation.
Another benefit of joining the European Union is the ability to arrest and try criminals who cross EU borders. Justice can be brought within an EU nation without having to go through lengthy extradition paperwork.
