Filing while waiting for Green Card..

My husband and I got married in May of 2024. He was here on a student visa until we eventually filed for an adjustment of status in Aug 2024. During this time he did not work and did not earn any money in any country. He did recieve a "work only" SSN because he was considering tutoring at his school but that never ended up happening. We finally got his green card in Jan 2025. 

 

Can we file jointly? What is he considered as? And do we need to file an FBAR (He has more than 10k in foriegn accounts)?
