Make sure that you are 18 years of age or older.
Reside in Canada for at least three years within the past four years. This will ensure your status as a permanent resident of Canada. However, this status can be jeopardized if you are the subject of an immigration investigation or inquiry, or if you have been ordered to leave Canada by the Canadian government. Avoid breaking Canadian immigration laws.
Maintain a clean criminal record. You cannot become a Canadian citizen if you have been convicted of a crime during your three years of permanent residency. Being in prison, on parole or on probation in Canada will invalidate your citizenship application. You will also be unable to apply for Canadian citizenship if you are under investigation for, are charged with, or have been convicted of a war crime or a crime against humanity.
Be able to demonstrate fluency in at least one of Canada's two official languages, English and French. You will be tested on your ability to communicate both in writing and in speech.
Be able to demonstrate basic knowledge of Canada's history, culture and government. Show that you have an elementary understanding of Canada's institutions, values and symbols.
Be 18 years of age or older.
Possess a valid "green card." A green card allows you to live and work in the United States legally.
Reside in the United States for at least 5 consecutive years prior to your application for citizenship. Absence from the United States for 6 consecutive months during that time will jeopardize your application. Additionally, you must have lived in your state for at least three consecutive months prior to your application.
Be able to demonstrate proficiency in English and basic understanding of the U.S. government and history.
File a Form N-400, which is an application for naturalization, at your nearest USCIS (United States Citizenship and Immigration Services) office. Include a photocopy of both sides of your green card, two passport photos and a check or money order for the amount of the fee ($680).
