Mr. Chair, to continue on with the previous questions, a full economic analysis of changes on language is not something the department has undertaken, but we have looked at other issues around language.
One of the things that we look at, of course, is where our comparator countries are on requirements for the citizenship test that they provide. If we look to the United States, applicants 18 and older must provide a language proficiency test or take a language proficiency test, which determines the applicant's ability to read, write, speak, and understand English; however, they're exempt from that if they're over the age of 50 and have spent 20 years in the U.S. or over the age of 55 and have spent 15 years in the U.S. In Australia, the age range is 18 to 59.
