To have applicant fees more closely reflect the costs associated with processing citizenship applications, citizenship processing fees will increase from $300 to $530 for applicants whose complete applications are received after Jan. 1, 2015. These applicants will benefit from the processing improvements outlined above, and this is in keeping with user-pay principles and a move toward full cost recovery in the citizenship program.
Applications for a grant and resumptions of citizenship to a minor are exempt from this change. The $100 Right of Citizenship fee for successful applicants remains the same. Other fees for services, such as for citizenship proofs, are not changing.
