Never ran into this.  Any suggestions?

Client works for a national non-profit organization and was transferred to Nevada.  His salary is funded by the CA office for three years.  W-2 issued from the CA office and marked CA.  Work is done in the  Nevada desert.  Visits CA for less than 3 weeks a year.  NO withholding for income tax.  He doesn't care about SDI (disability insurance).   All facts support he's a NV resident

Question: how to handle the filing with a W-2 issued by an office in CA marked as CA for the state?

File CA Part year resident in the year of move (2022) and CA non-resident return for the next few years?
