In recent years the government has instituted many reforms. It legalized political parties and trade unions, and legally guaranteed freedom of religion and assembly. There has also been a redefinition of the qualifications for Andorran citizenship, a major issue in a country where only 13,000 of 65,000 residents were legal citizens. In 1995, a law to broaden citizenship was passed, but citizenship remains difficult to acquire. Only Andorran nationals are able to transmit citizenship automatically to their children, a legal principal known as jus sanguinis. Lawful residents in Andorra who are nationals of France, Spain or Portugal may obtain citizenship after 10 years of residency. Other nationals may obtain citizenship after 20 years of residency. Children of residents may opt for Andorran citizenship after age 18 if they resided most of their lives in Andorra. Mere birth on Andorran soil, a legal principal known as jus soli, does not confer citizenship. Dual nationality is not permitted. Non-citizens are allowed to own only a 33% share of a company. Only after residing in the country for 20 years may they own 100% of a company. A proposed law to reduce the necessary years from 20 to 10 was debated in Parliament.
