Urgent, Taxes After Deferred Action(Daca)?

[patito1792 0]

If someone has, as stated on birth certificate, matriculation, and passport a

1=name+middle name+paternal last name+maternal last name.

However, before deferred action, the person has used only

2=name+middle name+paternal last name (no maternal last name).

and all the taxes filled previously were under that name.

How will someone file taxes if the SS# is under name+middle name+paternal last name+maternal last name.

Since it is different now, will the IRS think that both names are different if the USCIS knows that I have used 1=name+middle name+paternal last name (no maternal last name). I would think the USCIS will know that because I stated it under the application when I submitted it under "OTHE NAMES OR MADEN NAMES USED"

I'm saying this because the tax guy is telling us that we need to change our name now, but I don't think it makes sense to me and he is charging me more for having my name changes

Help please, as you see i don't have much time left.

Thank you so very much
