I was recently arrested and accepted a simple caution for common assault (assault by beating). The incident in question was domestic battery towards a family member. While common assault is a summary offence, the DV angle would likely make it a crime of moral turpitude in the US legal context. However I may be admissible under the petty offense exception, assuming the English statute and sentencing determined this?

I'd would be helpful to have some clarity of where I'd stand were I to apply for a US visa.
