To sum up my work history for 2021 as I realized that my original question had wrong dates in it (2019 as opposed to 2021). So the summary is:
1. Until 9/2021 I worked for CA office of my employee.
2. From 9/2021 to 2/2022 I worked from overseas for NY office of my employee (it's the same employee as previously in CA, I was just officially moved to NYC office). NY state taxes were withheld from my wages from this period of time.
3. I vested RSUs on 11/2021. NY and CA taxes were withheld.
4. I moved to NY in the February of 2022. I do not consider myself a residence of this state prior to this date.
Now, I want to understand how to handle state taxes related to my RSUS vest that happened in 11/2022 (point 3.) to avoid double taxation.
