21:04 Dzug, moral turpitude conviction or not (they are just more "anxious" about such convictions) the fact he has ANY conviction means he MUST apply for a Visa and is NOT eligible for the VWP."
As long as he can truthfully tick NO to the question on the VWP, then he can travel on the VWP. But, like everything else, CBP can deny entry to anyone, even with a visa issued from London.
The question
B) Have you ever been arrested or convicted for an offense or crime involving moral turpitude or a violation related to a controlled substance; or have been arrested or convicted for two or more offenses for which the aggregate sentence to confinement was five years or more; or have been a controlled substance trafficker; or are you seeking entry to engage in criminal or immoral activities?
Now, as he has 2 conviction, he needs to find out whether any are CIMTs, and if not, whether the district of columbia deem these crimes to have an aggrevated sentence of 5 years or more.
