my wife a Texan native married me in my home country united kingdom in 2011 but shortly had to return to the states for family matters.
6 months later i joined her in Texas on a 90 day esta visa but stayed in the country for over 2 years. 
I was arrested on a misdemeanor charge and spent 2 months in a deportation center whilst my consulate arranged for me to get back to the UK.
I asked why I was not taken to court for the misdemeanor and was told that ICE overrules state law and they just prefer to waiver misdemeanor charges as it slows down deportation proceedings.
I recall signing something that confirmed I volunteered to leave the country.
My question is how long is my ban from the USA?
is it worth me trying to overturn or get a waiver of some sort? or should my wife just apply to join me in UK?
