My son is a U.S. citizen. In 2020 he married a nonresident alien. They reside in the U.S. His spouse has applied for a social security number but it will be several months before she receives one. Can he file MFJ for 2020 even though his spouse does not yet have a SS number? If not, can he file as single for 2020 and then file MFJ in an amended return after she gets a SS number? Thank you for any information.
