I'm trying to confirm something that was mentioned to me.... I can't beleive it .... but it's so far fetched that it must be true.

Can someone tell me if this is right:

An immigrant is allowed to collect social security as soon as they
come to this country if they qualify? SS is not just retirement benefits.

For example: A (legal) immigrant family moves here and brings their parents who are elderly. This family can apply for and receive $ to take
care of the parents and possibly the kids. So just move here and we'll give you $$. Is this true?
