What is the FORM N-600 charge on my credit card?

What this charge usually means

A FORM N-600 line on your card statement is usually a U.S. government filing payment to USCIS for Form N-600, Application for Certificate of Citizenship. This form is used to request official proof of U.S. citizenship for someone who already acquired or derived citizenship through a parent. The charge is generally processed as a service payment, not a retail purchase, so statement wording can look brief or generic. In many cases, cardholders see only the form name, a shortened descriptor, or a payment-processor variation.

USCIS lists Form N-600 filing fees in its fee schedule and fee calculator. For general filings, the listed fee is commonly in the four-digit range (for example, paper filing and online filing amounts can differ). Because this is a government filing fee, it is typically a one-time transaction tied to a specific submission rather than a recurring subscription.

Why it appeared

• You filed Form N-600 yourself through a USCIS account or by mail with card authorization.
• An attorney, accredited representative, or family member filed on your behalf using your card details.
• You submitted multiple immigration forms and one line item posted as FORM N-600.
• A paper filing used Form G-1450 (card authorization), and USCIS posted the payment after lockbox intake.
• You are seeing a delayed posting date that does not match the day documents were mailed.

How to verify the charge

Start by checking your USCIS online account, filing receipt notices, email confirmations, and any package copy sent to a lockbox. Match the posted amount and date window to your filing records. If you worked with a preparer, ask for the exact form list and payment breakdown. You can also contact the USCIS Contact Center and confirm whether a payment was accepted for your case type.

If your statement includes a similar descriptor and you are unsure whether it is the same merchant, compare against known billing formats from other services, such as Patreon and Cash App, to avoid confusing unrelated charges.

How to cancel or reverse

For USCIS filings, cancellation is limited. If USCIS already accepted the filing, fees are generally final and nonrefundable under USCIS filing-fee policy, even if the case is later denied or withdrawn. If your package has not yet been accepted, you may still contact USCIS quickly to ask about available options, but reversal is not guaranteed. In practice, your best path is to verify status first, then decide whether to continue, withdraw the case, or proceed with corrected filings where eligible.

When and how to dispute

Dispute only if the charge is truly unauthorized, duplicated in error, or unrelated to any filing you approved. First, contact USCIS support to document what they can confirm. Then contact your card issuer and provide clear evidence: statement screenshot, USCIS notices, your timeline, and any identity-theft indicators. If you knowingly authorized a valid filing payment, a chargeback can create immigration case complications because unpaid government fees may affect case validity. Keep records of every call and written response from both USCIS and your bank.

If fraud is suspected, request a card replacement, monitor for additional unauthorized activity, and set transaction alerts. Acting quickly improves your chance of stopping follow-on misuse while preserving the documents your bank needs for investigation.
