Make the check payable to: U.S. Department of Homeland Security. Do not abbreviate this.To fill out the money order, you will need to "Pay to" U.S. Department of Homeland Security. A filing fee is required for many immigration forms. If you do not submit the correct fee, we will reject your form. Decide on the money order amount. 31, 2024, USCIS published a final rule that, for the first time since 2016, adjusts certain immigration and naturalization benefit request fees. The 'Pay to the order of' line should say 'US Department of Homeland Security' and the memo should say something like 'I-751 application and biometrics'. Do NOT sign the back of the money order. Leave that portion entirely blank.
