If I am a US citizen and i want to pettition a green card for one of my sibblings, what happens if he/she has overstayed his/her tourist visa? plus by the time his/her visa number is available from the NVC and he/she would have been years of overstaying the tourist visa, would they forgive that or just make him/her pay a fine?. I heard they forgive spouses, what about 'overstayed" sibblings of US citizens.
