@Angelo. LI, Sorry that your having an issue with depositing that check. You are correct. The app will only allow for domestic bank checks to be deposited. I did locate instructions on what to do with the check. Fees may apply. Hold may also apply. If you have specific questions don't hesitate to call or initiate a private chat to be certain you understand how long it takes and the cost involved. Thank you for reaching out.
1-210-531-8722 To initiate a private chat start with the HELP function on usaa.com or the mobile app and as you select the banking options, the option to chat will be available.
