You seem to have made a fairly complete review of your record. Expunged means expunged and short of a KGB/CIA/Mossad/ MI6 investigation or some other legal action I think you are better off leaving this little adventure off of any application.

The applications serve to seperate the unqualified and if they have a stack of people with no legal problems that week, guess who is going to stand out for their horrible offense against the state?

If in doubt talk to a real Lawyer, but my guess is he will tell you the same thing.
