You can grow old and die before Congress gets around to approving anything. Expect to wait years.
Most of the time, congress will aprove and send funds between 7-10 days. However, with this fiscal cliff and the elections that consumed the time and energy of most people, relief funds for hurrican sandy taken the longest out of all natural disasters to reach the people.
I regret I understand it can take several weeks after being approved checking all is in order. I enclose a link.
The money can begin to be disbursed within a matter of seven to ten days for claims which have been verified.
How long does it typically take to give out the money approved by congress? Like Katrina for example. How long did it take to send out the 110 billion approved by congress.
