Tips

  • Don't give up! Adjusting to life in the U.S. is filled with challenges and joys. If you reach out to others who want to help and keep taking concrete steps toward achieving your goal of becoming a citizen, you will succeed!
  • Be sure to practice "small talk" before you have your interview. That is, practice talking about the weather, asking how someone is doing, etc. This shows you can interact with others in basic English.
  • It is very important to read, understand, and be able to explain in your own words the "Oath of Allegiance". You can be asked about this at your interview. An ESL instructor can and should help you with this.
  • Be sure you memorize all the information you have given on your N-400 form. Know your permanent resident number as well as dates of departure and arrival for any trip you have taken outside the U.S. since becoming a permanent resident. Also, be able to provide the reason for the trip (business, vacation, to visit family, etc.) You can and will be asked questions taken from the information you give on your N-400 form, so be sure you know it thoroughly.
  • Interviewers at the citizenship interview will ask you questions from a list of 100 U.S. history and civics questions. You will be asked to answer the questions orally or in written form. You can learn the answers to these questions at the website to reinforce what you learn in your ESL class.
  • When you become a citizen, it's a good idea to register to vote and get your passport quickly.
  • For a list of N-400-related forms and contact addresses, visit the USCIS N-400, Application for Naturalization page.

Warnings

  • Don't trust everything people tell you. Practices change all the time, and much of the information well meaning people volunteer will be outdated.
  • Don't use any "Immigration counseling", "Green Card Service" or similar service unless it's run by a genuine immigration lawyer. Getting the wrong advice can hurt you!
  • Becoming a U.S. citizen (or even permanent resident) will have tax implications if you move abroad. So far, the U.S. is one of the only countries taxing on citizenship basis and not on residence.
