After you file

thanks for the reply. i accually no intent to claim EIC because i know i dont have any SSNat that time. but i was worry that if we ammend our 2021, 2021 filling status from MFS to MFJ,  it will effect for our child credit my husband alreay claimed under MFS because at that moment i didnt had any SSN/ITIN

but now i have my SSN we will ammend our 2020, 2021 tax returns filling status from MFS to MFJ

 

thanks
