interesting synopsis,
Safety and Security - Admissibility.
Read a not so recent article that said DUI/DWIs from other countries are are all considered felonies in CA, and having on ones record will prevent them from driving forever in CA.
Some misdemeanors may be exempted by a bond posted, ~$300 IIRC.
Also, dont try to bring in a CB radio unless its been properly disabled.
Not sure how up to date this info is.
