If your Visa card is showing as "Unverified" and you cannot set it as the default payment method, you'll need to verify the card first. Here's how to resolve this issue:

1. Open the AWS Billing and Cost Management console at https://console.aws.amazon.com/costmanagement/
2. In the navigation pane, choose "Payment preferences"
3. Find your unverified Visa card and click the "Verify" button next to it, then follow the prompts to complete verification

If you're still unable to verify the card after following these steps, you can try removing and re-adding the card:

1. Select the unverified Visa card and choose "Delete"
2. Choose "Add payment method" and enter your Visa card information again
3. Follow the prompts to verify your card

Once your Visa card is verified, you can set it as the default payment method:

1. Go back to the Payment preferences page
2. Find your verified Visa card
3. Choose "Set as default" next to it

Please note that you need to be logged in as the root user of the AWS account or have the necessary IAM permissions to make these changes. If you continue to experience issues, you may need to contact AWS Support directly for further assistance.
