I've got a queation somebody might be able to answer. . .
How do they (US immigration) know if you have been arrested / cautioned ?
I was arrested many years ago (wrongfully) on suspicioun of theft from a motor vehicle. I was also arrested (legitimately) and cautioned for posession of cannabis.
I've been to the US a few times, and simply don't mention these on the form. They happened years ago, any caution is long spent and I sincerely doubt they are still held on any police databases. I've never been stopped from entering the country.
The future's bright, the future's blue and white.
