You will have to file separately again. You both are still considered as a nonresident. Per IRS, you are treated as passing the green card test hence a US resident ONLY IF you are given the status by the USCIS with an alien registration card on the Form I-551, the
United States Permanent Resident Card
. See
Green Card Test
.
Since TurboTax does not support nonresidents, you can visit Sprintax like last year.
