First, your return must be accepted by the IRS. If it was rejected or is pending, the advance hasn't been processed yet.
Then, your advance request goes to the underwriting bank, which may accept or decline, you should receive an email either way.
"You will receive an email with instructions on how to create your online account. Once your online account is set up, you will receive temporary card information that you can use to spend online.
