My daughter goes to Med School in Philadelphia (Pennsylvania) and we (her parents) live in California. She helped out with research at school (remotely) during summer and was also working a job in California during summer. She has 2 W-2s - one from California and one from Pennsylvania. Which state is considered as non-resident for her - California or Pennsylvania? I found this on PA website, but would like to get some confirmation.
Parents live out of state, I work and go to college in PA. (custhelp.com)
