He's more a libertarian "free trade with the whole world" person. eg
The Telegraph’s Stephen Bush has suggested that there are in fact “two UKIPS”: one, libertarian and right-wing, the other, working-class and anti-immigrant. Nigel Farage, he feels, straddles these two sides quite effectively, while UKIP’s new MP Douglas Carswell sits more firmly in the former camp (although it must be said that he seems to be very popular with many of his working class constituents). This is not entirely unproblematic of course—many of the libertarians within the party are also highly critical of mass immigration (not least Carswell himself)—but it is an interesting distinction that seems to capture something about the peculiar nature of the party. What is less clear, perhaps, is where conservatism sits in this schema. On the one hand, we might think it closer to the libertarian side, sharing a commitment to the free market and individual liberty. On the other, we might consider it more at home with the working-class anti-immigrant grouping, suspicious of the changes to traditional ways of life that globalisation has wrought. As we will see in the next section, it is this latter sentiment that some in the Labour party have woken up to, leading conservatism to find some seemingly unlikely champions on the left.

No longer a mere protest party, we won the European elections and showed that we have what it takes to win seats in parliament. Ahead of May’s general election, we now have to show the whole country that we have what it takes to win big. That means an optimistic, internationalist and inclusive agenda for the whole country.”
Carswell wrote: “Preparing for the future means putting in place an immigration system capable of saying a cheery, welcoming ‘yes’ to doctors from Singapore or scientists from south Asia, and a polite ‘no, thank you’ to someone with a criminal record, or an inclination towards welfare dependence.
