Australian Prime Minister Malcolm Turnbull announced on Thursday local time that the country will enhance its citizenship rules to reflect national values.

Foreigners who wish to apply for naturalization will have to meet higher English language standards, provide proof of integration like a job, and have been permanent residents for at least four years.

The current policy requires only having lived in Australia for one year before applying for citizenship.

The reformed test will also do away with the multiple-choice format.

Immigration Minister Peter Dutton vowed more police checks on citizenship applicants and ordered applicants with a history of domestic violence be automatically disqualified.
