A few facts:
1. You'll have no choice other than to 'forget' about your conviction on the visa waiver form. You need to allow at least 5 months for the entire visa application process; there's no 'fast track' system ;
2. European human rights legislation prohibits the UK government from passing on personal data about its citizens (including criminal records) to other authorities (including the US immigration service) without 'justifiable cause'. Information can be shared about suspected drug traffickers, terrorists, etc but the database of UK criminal records can't be shared with the USA.
3. The USA has no direct access to any criminal records, other than its own and those of Canada. (The two countries share a common database).
4. There is nothing in the digital data on a passport which isn't already visible to the naked eye. (i.e. the digital data only records your name, date & place of birth, etc. It merely proves that the printed information hasn't been altered).
5. Several people have posted on AB, to state that they've entered the USA, under the visa waiver program, despite having criminal convictions.
