What convictions and sentences do you have and when did they occur please?
Thanks for your question. I will try to help.
The good character requirement is here:
However, you simply prove the requirement by answering the questions asked about convictions/precious behaviour in the application form when you apply for naturalisation.
If you do not have any criminal convictions or multiple civil judgements or bankruptcy against you then you will meet the requirement and it will not be an issue.
My goal is to provide you with a good service. If you feel you have received anything less, please reply back. Please remember to leave positive feedback using the stars at the top of the page.
