OK, here is my situation, I am filing I-130 & I-485 for my wife, but both of us are unemployed student, If I can find another sponsor can fully covered her then do I still need to file I-864?
If I still have to file I-864, I dont have W-2 or employment letter, I dont even know what is 1099. should I just file I-864 without those materials?

and do we have to file I-131 with I-485 concurrently or we can file I-131 when we really need it?

Thanks a lot!

Yes. File it without W-2s and/or 1099s, but still file it.
