As secuality gets tighter, and the economy grows at a slower rate, or even shrinks, immigration will go down and the birth rate will decrease. The changes to the INS under Homeland Security are massive, though change does not happen all at once, but the net effect will be immigration will be more difficult in the upcoming years.

As for housing, sorry, but without job growth, housing will maybe not collapse, but will go down in value.

First of all, birth rates drop more with prosperity and increase with poverty. Second, making immigration more difficult means that the US only grows by 35 million in the next decade instead of 40 million. Net result is still more people to house.
