If your wife was on an F1 visa during 2021 (until November 2021), she would generally be considered a non-resident alien for tax purposes, unless you made a special election for her to be treated as a resident alien for tax purposes.
If you did not elect for her to be treated as a resident, then you should have filed separately as Married Filing Separately or Married Filing Jointly only if you made the election for her to be treated as a resident. Without this election, your joint filing might not be appropriate for the 2021 tax year.
Since you filed jointly, you might need to amend your 2021 tax return (Form 1040X) if your wife should have been considered a non-resident alien, unless you made the election to treat her as a resident. If you did not make the election, filing jointly in 2021 might have been incorrect.
Did you make the election in 2021 for her to be treated as a resident?
