@naida_softic ,
(a) is your spouse living with you or is she in her home country ? If so which country ?
(b) does she have a tax id ( ITIN ) -- whether she is living here in the USA or not ?
While your answer to my questions may modulate my answers a bit , but in general :
1. She needs a tax id to be able to file with you ( ITIN request W-7 )
2. For MFJ ( and thereby get the full standard deduction at least ), her world income must come under US tax.
3. If she is abroad and has income, her income may be excluded under Foreign Earned Income Exclusion
But all of the above would need you to file by mail.
I will circle back once I hear from you
