Does immigration hurt support for the welfare state?

Here in the United States, opponents of immigration reform frequently talk about the dangers of rewarding people who came without authorization or the prospect that immigrants might take jobs from native-born Americans. But there is another concern about immigration that they don’t typically raise, one that you are more likely to hear from the European left than the American right: that immigration undermines the social welfare state by making voters less supportive of public spending.
