My spouse is a non us citizen and neither residence, i have selected Married Filing separately Head of the house still wont go forward, cause of SSN for my spouse.

You can try typing NRA in as your spouses last name.  Make sure you put a check mark in the box that says My spouse is a Non-Resident alien in the My info section. When you get to the end and try to transmit the return, ignore the e-file errors regarding your NRA spouse and select transmit your return. If that does not work you will need to print and mail your return and write NRA (Non Resident Alien) in the space for their SSN.
