Just to clarify, is NY your husband's permanent home, i.e. state of legal residency? Is he registered to vote and licensed to drive in NY?

 My husband's permanent home is in NY state.  He is registered to vote and licensed to drive in NY.  However, he has been living and working out of US since 2019.  His residence of 2020 is not in NY.
