Thanks. But to me, this is out of a common sense: Brothers or sisters can take their spouse and children to immigrate together, but the immediate relatives - father, mother or spouse cannot. This could give better immigration benefits to brothers and sisters than to the immediate relatives and then treat them much better than the immediate relatives. How could the Congress make such a law? What is a rationale to make the law? This is why the I-130 instructions confuse me.
-Just think about it: the immediate relatives of US citizens do not need to wait for the immigration visa number and thus, they can get their green card very soon, but the non-immediate relatives have to wait for several years for the priority date to be current to get the green card.
