Renewal certificate: I renewed 2 months ago, and I did not receive my renewal certificate. Why?

Please check the end date of your active certification. Your certification is valid for 4 years from the date of award (which is the date of passing your relevant exam). Your certification renewal certificate is emailed to you within 4 weeks of the end date of your active certification. So even if you renewed the certification ahead of time, the certificate will be emailed only after the current certification expires. If you need an official proof of maintaining your certification while you are waiting for the certificate, please download a pdf file from the online National Interpreter Registry. Search by your name, and in the results area, click on the down arrow  on the far right, to view and download the proof of your certification status.
