This is the U.S Citizenship Self-test for you and for other people who are refugees and want to become a U.S Citizen in the future, (After living a period of 5 years in the U.S). 
There are 100 questions and answers, which are very crucial that I think you should know before you take a real exam. These questions are divided into 5 pages. Each page contains 20 questions.
The source of this information was taken from a Vietnamese Newspaper named Rang Dong. The reason why I spend time to create this program is to help you and other people (and me too!) to prepare well for taking the U.S citizenship test. Therefore, if you find any mistake in the test, or, if you have any other helpful information about this topic, please feel free to let me know as soon as possible. That would help me to make the test more efficient and perfect. I appreciate your contributions and am very thankful to you.
Please note that this program is free and non-profit. However, you are not allowed to copy, modify or link this Site to yours. If you attempted to do so, you would definitely be responsible for the damage of this program.
