You will get an email update when your visa application decision has been returned to the Visa Application Centre. If you can't check your email easily or want more detailed tracking information, you may be able to receive updates via SMS on your phone. Please confirm if this service is available at the Visa Application Centre you are visiting.
Furthermore, you can track the status of your visa application online by using the Reference Number, which is mentioned on the invoice/receipt provided by the Visa Application Centre, along with your last name.
