Arizona has opted out of the federal bankruptcy exemptions,  
but the opt-out applies only to its residents. Therefore, if this
state is the applicable state (as determined by the method
stated on the home page of this site), the debtor may use the
federal exemptions if the debtor is not a resident of this state
on the date of filing bankruptcy.
In re Rody, 468 B.R. 384
(Bankr. D. Ariz. 2012) (because Arizona opt-out applies only to
Arizona residents, non-resident may use federal exemptions).
