Hi, I am in a similar but slightly different situation. I am on a J-1 visa and have filed taxes as a non-resident alien in 2022 and 2023, and I have to file taxes as a resident alien in 2024. My wife and two children arrived at the same time as myself, and they are resident aliens but do not have SSN or ITIN.
What are the advantages of applying for an ITIN, and would it be possible to go without applying for it? We are leaving the US this year, so I do not want to apply if it is too much of a hassle.
