8 C.F.R. § 106.1 – Fee requirements.

(a) Fees must be submitted with any USCIS benefit request or other request in the amount and subject to the conditions provided in this part and remitted in the manner prescribed in the relevant form instructions, on the USCIS website, or in a Federal Register document. The fees established in this part are associated with the benefit, the adjudication, or the type of request and not solely determined by the form number listed in 8 CFR 106.2.
(b) Fees must be remitted from a bank or other institution located in the United States and payable in U.S. currency. The fee must be paid using the method that USCIS prescribes for the request, office, filing method, or filing location, as provided in the form instructions or by individual notice.
(c) If a remittance in payment of a fee or any other matter is not honored by the bank or financial institution on which it is drawn:
1. (1) The provisions of 8 CFR 103.2(a)(7)(ii) apply, no receipt will be issued, and if a receipt was issued, it is void and the benefit request loses its receipt date; and
2. (2) If the benefit request was approved, the approval may be revoked upon notice. If the approved benefit request requires multiple fees, this provision will apply if any fee submitted is not honored. Other fees that were paid for a benefit request that is revoked under this provision will be retained and not refunded. A revocation of an approval because the fee submitted is not honored may be appealed to the USCIS Administrative Appeals Office, in accordance with 8 CFR 103.3 and the applicable form instructions.
