S/O flew here to US and married in August 2023
Staying in Calfornia
Had income in Canada before marriage, but no income since arriving in US
Did not receive green card until Feb 2024
I didn't have any income for 2023, and she hasn't had income since marriage
So no sure if filing taxes is needed as income was only before marriage, her home was in Canada, and she didn't have a green card until this year
Saw some people filed jointly, some separately
Saw Form 8958 and Form 2555 mentioned
Any help would be greatly appreciated
