In which case a residence card could be revoked?

[Memito]

Hi guys there is something I would like to ask you.
My wife has got a residence card expiring on December 2015.
From 8 of June I m without work and not registered at the jobcentre, but actively looking for a job and I am just waiting to be offered a new job if GOD wants.
Since February my wife is an "italian citizen" but my question is that:

1) As I m not working since 8th of June, what happens to her residence card?
2)If in the future I will apply for a EEA pr can they say the residence card was not valid from 8th of june or not valid at all for the purpose of permanent residence?

If your wife is an Italian citizen, she does not need a residence card to live and work in the UK. She can do so based on her Italian passport.

That is fine so long as you have proof that you are actively looking for a job (such as emails applying for jobs, invitations to interviews, etc). I would recommend registering at the Jobcentre though, it makes it easier to maintain the requirement of "job-seeking" from the perspective of exercising treaty rights. Otherwise, your PR clock will reset.
