My wife, without my knowledge and permission, filed for her siblings for GC (12 in total). I just found out about it when I saw the letter from INS requesting more details (like birth certificate etc). I am just curious to know who can this petition be cancelled and how far along it in is in the process (keeping in mind that INS has just requested birth certificates etc). My wife doesn't work at all so she will have to use my income as proof of income. Because we do joint tax returns, can she use our tax returns as proof of income although she has no income. At what stage she would have to provide proof of income and if she sign affidavit of support, would I be held liable for it? Is there a way to tell INS that I am against this petition because I am the sole bread earner?
