Having your ILR refused can be devastating, but it is important to know that you can act on this.
Should your ILR get refused, you can submit a new ILR application that clearly addresses the grounds for refusal. This gives the Home Office the chance to review your request and reconsider.
There are multiple common grounds for refusal, which include: excessive absences, immigration breaches, failure to disclose debt, criminal convictions, failing the English language test, or, any other adverse behaviour.
You can seek immigration advice from a trained lawyer should your application be refused.
