" There has been a significant increase in decisions by the Home Office to deprive British Citizens of their Nationality in the past few years. Although a small number of cases attract a lot of media publicity, many of the recent decisions taken involve clients who have no criminal record such as Albanian nationals who obtained refugee status and citizenship on the basis of an asylum claim based on Kosovan identity. 

We have represented many clients in this area, and successfully challenged decisions by the Home Office to deprive citizenship. We have also successfully obtained British passports for clients in their correct identity who would like evidence of their identity whilst their deprivation appeal is ongoing. Deprivation of Citizenship appeals are complex legal proceedings and it is important to get the best legal advice to assist you with your legal challenge. "

Can I challenge a decision to deprive me of citizenship?

If the Home Office decide to deprive you of citizenship, you will have a right of appeal in respect of that decision. It is however important to get legal advice before you pursue an appeal to assess what the prospects of appealing would be. There are certain issues that can make a decision to deprive unreasonable (for example if there was a long Home Office delay before a decision was made, or if you were a child when you obtained indefinite leave to remain). Each person’s situation is different so it is important to get advice from an experienced professional to see whether you may have a strong case for challenging a deprivation decision.

If I am deprived of citizenship will I have to leave the UK?

A decision to deprive someone of citizenship is different from a decision about whether that person should be allowed to remain in the UK or not. If a person is deprived of citizenship, the next stage is for the Home Office to decide whether that person should be allowed to remain in the UK. This decision is usually taken by a specialist team within the Home Office called the Status Review Unit. The person concerned will have a chance to write a letter to the Home Office explaining what ties they have in the UK and the reasons they should be allowed to remain in the UK.


What does it mean if my right to appeal is to SIAC?

There are certain types of decisions that the Home Office may take where they consider it is not in the public interest to disclose the full basis for the decision. This may be in national security decisions, or decisions involving individuals who are involved in Serious Organised Crime. If such a decision is taken, then the person will have a right of appeal to a specialist Tribunal known as SIAC (the Special Immigration Appeals Commission). These types of appeals are extremely complex and it is vital that a person who receives such a decision receives specialist advice from an experienced immigration advisor. If you have received such a decision, Mark Lilley-Tams and Emma Cohen have experience of these types of matters and will be able to advise you further.
