Ah, I’m so sorry that happened — USCIS can be really quick to reject for payment issues, even if the intent is clear. When this happens, they usually send the whole package back within 2–4 weeks. If you haven’t gotten the package yet, I’d wait a few more days before deciding whether to refile. If the rejection notice includes instructions, you may be able to resubmit without starting over. Let us know when it arrives and what it says — happy to help you from there.
