Do you need to file I-864 for your son if you are a us citizen?

Yes, if you are a U.S. citizen and are sponsoring your son for a green card, you need to file Form I-864, Affidavit of Support. This form demonstrates that you can financially support him and ensures that he will not become a public charge. It is a required part of the Immigration process for family-sponsored immigrants. However, if your son is a minor and you are his parent, you may also have other options that could exempt him from needing an affidavit.
