J-2 spouse with zero phyical presence and zero US income

Hi,

 

My wife, who was a J-2 visa holder (I still have J-1), left the US in 2024 and most likely will have zero physical presence and zero US income in 2025. We requested early closure of her J-2 visa in August 2025.

 

We did joint return for tax year of 2024 as we both had US income and met substantial presence test.

Does she still have any tax filing obligation for 2025 even if she has zero physical presence and zero US income in 2025? If not, can I just do "married filing separately"?

I was wondering if our previous filing status still continues becasue I still have valid J-1 and am staying in the US.
