If your spousal sponsorship or even any other family sponsorship application has been rejected, you may be able to appeal, but this depends on the stage. If the application to sponsor was rejected, you might not be able to appeal. However, your Canadian relative can appeal if your permanent residence application is rejected and you are still in the UK.
They can submit the appeal to the Immigration Appeal Division (IAD). You will get the information on how to go about this in your rejection notice.
If you are unable to appeal or you are unsuccessful with your appeal, you can consider other immigration options. We can help review your rejected application and eligibility to advise on the best steps to take. Call us on 0333 305 9375 to get started.
