Travel to USA - Criminal Record

[westyorksman]

Hello - i have a criminal record for GBH without intent - it is my only conviction and although I did not go to prison I am aware the record will be with me for 10 years (due to suspended sentence). I may have to travel to the USA with work for a few days and although I am aware I am not allowed in to the country, I was wondering if anyone knew what the chances are of me getting in simply by not saying anything in the hope they dont check? Do they check every single person going in to the country? Many thanks.
