After you file

Unfortunately, I did not file an extension because I had to do my tax early so I can sponsor my spouse. So I guess there is no point to amend if I will not get money back. 


You might benefit from the lower tax rate for MFJ, as long as your spouse does not have foreign income that will need to be included.  You just won't get any of the extras that require a valid SSN.
