Children and youth compose a significant portion of the U.S. immigrant population and often qualify for various forms of immigration relief, many of which involve an application filing fee. Under the Trump administration, USCIS promulgated a final rule intended to dramatically raise fees for many immigration application forms, including those available to young people, and would have limited access to fee waivers. The rule was blocked by federal courts, and after President Biden took office, the Department of Justice decided not to defend the rule, so it never took effect and for now immigration filing fees remain at the previously set amounts. This advisory reviews some of the main forms of immigration relief available to children and youth and the current fees for each, and summarizes the litigation and related efforts that ultimately defeated the Trump fee rule.
