Why must United States citizens fill out I-9 forms?
It is the law. The I-9 Form is designed to determine who is authorized to work in the United States. Its purpose is not to determine who is, and is not a citizen. While all citizens are authorized to work in the United States, it is not always easy to recognize who is, and is not a citizen. We are a diverse people drawing our heritage from every country in the world. Employers cannot simply look at new hires and determine, “who needs to complete a Form I-9, and who doesn’t.” For this process to be effective, everyone must complete a Form I-9.
