Can You Hold Both Canadian and U.S. Citizenship
Canada generally allows dual citizenship, so you can usually keep your Canadian status when you become a U.S. citizen. The U.S. does not require you to renounce Canadian nationality, and Canada does not automatically strip your citizenship for acquiring another passport. However, some countries do not recognize dual status, which can affect how your citizenship is treated abroad. You should confirm the latest rules with official government sources before making decisions. You can read the official Canadian government guidance on dual citizenship here Canada dual citizenship rules.
U.S. law does not force you to give up foreign citizenships when you naturalize, but you may face obligations in other countries that do not permit dual nationality. For example, some nations cancel your original citizenship the moment you voluntarily adopt another. If you plan to live or work outside the U.S., check how each country treats dual status. You can review the U.S. Citizenship and Immigration Services information on dual nationality here USCIS dual nationality.
What Happens When You Become a U.S. Citizen
The naturalization process requires you to swear an oath of allegiance to the United States, but the oath does not explicitly demand you renounce other citizenships. You must meet residency, language, and civics requirements, and you must pass a background check. After approval, you receive a U.S. certificate of naturalization and can apply for a U.S. passport. The U.S. government recognizes that you may remain a citizen of another country, depending on that country's laws.
Some people worry that taking the oath automatically cancels their Canadian citizenship, but this is not how Canadian law works. Canada treats your oath to the United States as a personal commitment, not as a legal renunciation of Canadian status. You can keep your Canadian passport and your U.S. passport, provided you follow the rules of both countries. You can read the official U.S. naturalization overview here USCIS naturalization process.
Practical Implications of Dual Canadian-American Citizenship
As a dual citizen, you can live, work, and own property in both countries. You may be subject to taxes in both the United States and Canada, because the U.S. taxes worldwide income even if you live abroad. You should understand reporting rules such as the Foreign Account Tax Compliance Act and the Canadian reporting requirements for foreign assets.

Travel, Voting, and Consular Access
You can travel with either passport, but you must enter and leave the United States using your U.S. passport and enter and leave Canada using your Canadian passport. You may vote in U.S. federal elections and in Canadian federal and provincial elections if you meet residency and registration rules. You can also access consular services from both governments if you are abroad. You should keep both passports valid and follow the entry requirements of each country.
Tax Filing and Reporting
You may need to file tax returns in both countries each year and report foreign bank accounts and assets as required. Canada and the United States have tax treaties and information-sharing agreements that affect how your income is taxed. You should use qualified tax professionals who understand cross-border rules to avoid penalties and double taxation.
Military Service and Obligations
Dual citizens may be subject to military service obligations in either country depending on local laws and historical conscription rules. You should
