The cost of applying for U.S. citizenship is about to rise. More than 9 million legal permanent residents in the United States are eligible to apply for U.S. citizenship but haven’t done so, according to the Office of Homeland Security Statistics. On April 1, the cost of the application to naturalize is climbing as much as 19%. The price of getting a green card will jump, too. The changes are a fraction of the fee increases sought by the Trump administration before a federal judge scrapped them. Still, immigration attorneys say, immigration costs almost always trend higher, so those who want to naturalize for less should consider submitting an application before April 1.
