I am married to a non-resident alien and I am a Lawful permanent resident (LPRs). Can I file a 2021 tax return as married filing jointly? I have already sent an application for ITIN for my wife, but then I realized I have to send my federal tax return along with it. Should I wait if ITIN to process successfully or mail my federal tax return or file an extension if ITIN takes longer than expected?
Any suggestion or answers to the above question is really appreciated. Thanks in advance
