thank you guys, my co-sponsor just found his birth certificate, and also i don't need the w-2 form, because it's only needed if he filed jointly his tax return, but since he filed individually i don't need it, I called the ins and they told me so.
the INS really sucks, they just tell you things even if they're not sure about it, they told me before that I have to submit the w-2 forms otherwise i can't file, but today i was reading the instructions about the affidavit of support and i read that you have to submit the last tax return and w-2 only if you're filing jointly the tax return ..... so i called them i talked to a different person and she said the same thing that was written in the instuctions, I don't know why the first person wasted my time and made me wait all this time to find the missing w-2 form, he could have said i don't know, that's how they do all the time , just talk about stuff that they don't know about instead of saying i don't know let me transfer you to someone who might know . it's not the first time it happened, whenver i talk to them they give me two different answers,
anyways thank you guys i will file tomorrow wish me luuuuuuuuuuuck! that's I'm filing now MTR motion to reopen , so I'm really worried. I was already denied. good luck to all of you.
