British Citizenship

[Joefdo]

Hello there,
I'm about to apply for my British citizenship and I'm bit worried my past migration history effect my application. I have been living in UK since 2001. I came to UK on working holiday visa for two years but I did not return to country of origin and overstayed in the UK. In 2008 I got married to a EEA national and I was granted 5 year visa as a family member of EEA national and now I have a permanent resident card. My problem is, on AN application asks about working history for last ten years and I'm not sure what should I do. I did work for an agency between 2003 to 2009 but I don't know It has been recorded in inland revenue. Please advice me what to do?

If you had a period of illegal residence prior to 2008, you won't be able to apply for BC until 2018.
