On January 30, 2024, USCIS announced the final rule for an adjusted fee schedule. The changes to fees impact many categories of applications and will go into effect on April 1, 2024. Anything postmarked on or after April 1, 2024 will be subject to the new fees. To apply under the current fee schedule, applications must be postmarked before April 1, 2024.
