Hi,
I have been married since 2021 to a non-resident spouse that did not have any SSN or ITIN, i have been filing my taxes as single, now she has recently received her green card and an SSN, i need help and advice on how to amend the tax returns of 2021, 2022, 2023 to include her tax returns and file as married jointly?
Any help is appreciated.
Thanks in advance.
Regards
