What exactly do you mean by "immigration policy"?
Because I'm quite sure that, whereas both sides agree that entering the country illegally is, well, illegal, the parties differ on how to deal with immigration. Democrats tend to favor giving immigrants better access to education, whereas Republicans take a harder line towards them.
EDIT: Also, on economics, Republicans favor spending lots of money with less taxes (also spending more money on defense), but Democrats spend lots of money with more taxes (spending more of the money on fair trade and education)
Move past the rhetoric and the action is all the same. Movements exist in both parties to provide amnesty and benefits to illegal immigrants. And their greatest proponents are George W. Bush and John McCain. I could name even nuttier Republicans *Lindsey Graham*. Also, neither party has assumed the responsibility of securing our borders. Complacency is therefore the policy of both. They say it is unattainable, but that is hogwash. If we had the will, we could bring illegal immigration to a trickle in a matter of months.
On economics, that sounds like a pretty paltry difference to me. And it's outdated, considering George W. Bush made huge increases in education spending and Obama claims he intends to cut taxes for most Americans. Bush, McCain, and Obama all introduced, or would have introduced, tax cuts and unprecedented spending. The differences between Republicans and Democrats are, in part, a ruse. It is all rhetoric. They fight for control and rage over peanuts, but there is little substantive difference between them that makes any difference to most Americans.
EDIT: Sorry for being so far off topic.
