Difficulty figuring out if tax filing needed, and if not, should even be done

[ER-NA 0]

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

Just found this comment, and seems like the best answer i've found so far

We always filed our taxes (jointly) no matter income or not, for immigration purposes - we did this before I even had a status in the US. It just felt a lot easier having tax return transcripts for ALL years. That was extra evidence of a bonafide marriage for both ROC and Citizenship, and we never had to deal with any immigration officer questioning us why we didn't file taxes some years. 

I actually never disclosed my foreign income I got the year I moved to the US, neither did I disclose the condo I sold before moving. It's not like I made a lot of money, and I know it should've been disclosed, but we skipped it as it seemed like too much trouble. This was ~8 years ago now.

Yeah filing for the extra evidence was the main reason I was thinking. Don't want to regret not doing something down the line when it could be helpful.
Thanks for your input!
