Well, i saw so many guys with criminal convictions getting their visas - some had one, others had few convictions in the past - none crossing the 12 month custodial sentence requirement. I think barrystock gonna be all right with his visa.
Mingi Reigo - you may have some issues, as indeed, they consider suspended sentences as custodial sentences, but can you clarify, do you mean "suspended sentences", "conditional discharge" or "Conditional sentence". These are three different things (well, at least in the UK Criminal Law)
In case of a conditional sentence it may mean such things as community service for example or curfew - so in a case if a person is convicted to 360 hours of unpaid work then this person may be given 2 years to complete this. In such a case it will not (i assume so at leat) be considered custodial sentence of over 12 months.
Good luck guys
