These include people who have been arrested, even if the arrest did not result in a criminal conviction, those with criminal records, (the Rehabilitation of Offenders Act does not apply to U.S. visa law), certain serious communicable illnesses, those who have been refused admission into, or have been deported from, the United States, or have previously overstayed on the VWP. Such travelers must apply for special restricted visas. If they attempt to travel without a visa, they may be refused entry into the United States.
http://www.usembassy.org.uk/cons_new/visa/niv/add_crime.htmlApplicants applying for visas at the U.S. Embassy in London or the Consulate in Belfast are required to furnish a police certificate from the Association of Chief Police Officers (ACPO) issued within 6 months of the date of the visa interview. Information on obtaining the police certificate is available from the ACPO website.
Applying for the visa
You are required to schedule an appointment for an interview with a U.S. Consular Officer.
Applicants applying for visas in London are required to request an appointment with the Visa Coordination Officer to allow sufficient time for their case to be reviewed, as their application will be subject to greater scrutiny. Applicants with criminal histories who do not request an appoitment with the Visa Coordination Officer may be required to return to the Embassy at a later date if there is insufficient time to evaluate their case.
When applying for a visa you are required to submit with your application the following additional documents:
* a completed personal data sheet, Form VCU1 (PDF 64Kb);
* A police certificate from the ACPO issued less than 6 months before your visa interview;
* copies of the court record(s) covering all charges of which you have been convicted, or which are presently pending against you, if relevant. (Required if you have a conviction outside the United Kingdom or your ACPO states "No Trace" or "No Live Trace" or does not list in full your arrests/convictions/cautions).
If the conviction(s) results in the applicant being found permanently ineligible to receive a visa, it will mean a lifetime exclusion from the United States unless he or she obtains a waiver of the permanent ineligibility from the United States Department of Homeland Security Customs and Border Protection (DHSCBP). The granting of a waiver is not automatic and is based on several factors, including nature of the crime committed, sentence served and the period of time which has elapsed since the conviction.
