What is the AOS FILING charge on my credit card?

What this charge usually means

The descriptor AOS FILING is commonly associated with immigration-related filing help, usually tied to Adjustment of Status (often shortened to AOS) paperwork or a service that assists with submission steps. In many cases, the charge is not from your bank itself but from a third-party preparer, filing assistant, law office billing processor, or payment intermediary. The wording can look generic on statements, so it may not exactly match the business name you remember from checkout.

If you expected a government filing fee, review your receipt details carefully. Some payments include separate amounts for professional service fees and official filing fees. That split can cause unfamiliar statement text even when the transaction is legitimate.

Why it appeared on your card

• You paid for document preparation, filing support, or case-packaging help.
• A family member used your card for an immigration-related filing service.
• You agreed to a staged payment plan where each step posts separately.
• The merchant used a different legal entity or processor name on card networks.
• The charge could be unauthorized if no one in your household bought such services.

How to verify the transaction

Start with your email inbox and SMS history for receipts, confirmations, onboarding messages, or appointment notices around the transaction date. Match the billed amount and date against any signed service agreement. If you have an account portal, check invoice history and payment method logs.

Next, call the number on the back of your card and ask your issuer for any additional merchant details attached to the authorization, such as location, acquirer reference data, or a phone number. This often identifies the actual business behind a shortened descriptor.

It can also help to compare this with other commonly confusing descriptors, such as Patreon or Cash App, where the statement text may differ from the brand customers recognize.

How to cancel and prevent future charges

If the payment is valid but unwanted going forward, contact the service provider first and request written cancellation confirmation. Ask for three things: cancellation effective date, whether any pending charge will still settle, and whether your card token has been removed for future billing. Keep screenshots or emails for your records.

Then remove saved cards in the provider portal, if available, and set card alerts in your banking app for new card-not-present transactions. If the merchant cannot confirm cancellation, ask your issuer to block future attempts from that merchant profile.

When and how to dispute

Dispute promptly if the charge is unfamiliar, duplicated, or inconsistent with what you authorized. Use your bank’s fraud/dispute channel and provide: transaction date, amount, why you believe it is invalid, and any supporting evidence (emails, contracts, cancellation requests, or proof of no service delivered). Filing early improves your chances of a cleaner investigation timeline.

If the charge was authorized but the service was not delivered as promised, describe it as a service issue and include documented attempts to resolve it with the merchant. If it was not authorized at all, report it as fraud and request card replacement to stop repeat attempts.

Because AOS FILING can represent multiple service providers, treat any unexpected charge as high-risk until verified. Confirm fast, document everything, and escalate through your issuer if the merchant is unresponsive.
