Ríos Azul

Hello, I recently requested a statement of my National Insurance Contributions, and the status on my account says that the request is "complete." However, I haven't received the certificate yet, and I'm not sure what happens next. Could you let me know how I will receive it? My main postal address is in Spain, so I’m wondering if it will be sent there or if there is any way to access it digitally or print it myself. Thank you for your assistance!
