I wouldn't go so far as to pigeonhole 'Jewish teaching' - which is very far from the monolith a lot of these Jewish outreach people caricature it as - to one side in the contemporary American immigration debate. You see, while Halacha clearly sets limits on the entry of idolaters to the Land of Israel, it's worth noting that these restrictions are unique to (a) a Jewish State (b) in the Land of Israel. Simply put, neither Jewish thought nor Jewish law really care to dictate for gentile nations - with the exception of the seven laws, of course.

But even if we were to assume that the Jewish laws pertaining to God's 'Kingdom of Priests' are indeed applicable to our western nation-states, I suspect that we would find them more open to immigration than the populists who style themselves "conservatives" might like. As per Maimonides (and really the Talmud, if you want to just go back to Maimonides's source), a gentile who formally accepts to worship the One and refrain from idolatry is considered a Ger Toshav, or resident alien, and he is granted significant rights and is considered a part of the general commonwealth. 

In other words, so long as a gentile accepts God's sovereignty - which is of course the primary (the only?) constitutional principle in the Jewish commonwealth - he is granted the right of residency and significant social rights. In my opinion, at least, that exemplifies a far more expansive view of immigration than the linked speaker suggests.

But this is all assuming that God's instructions for his own commonwealth are equally relevant to the gentile nations. In reality they aren't, and as such every nation has the moral right to decide what the measure of its sovereignty is and what it takes to become a member of that nation. The Torah is only very narrowly applicable to the gentile nations, and I believe that turning it into a partisan cudgel only demeans its sanctity and debases it. It is analogous to cutting up a beautiful tapestry and using it as toilet paper.

Yes, we can look to the Torah for general moral guidance when we form our political opinions, but only insofar as it teaches us how to be men and walk in God's ways. Politics is a far more trivial subject than how to be men and walk in God's ways. God revealed himself to give men guidance on how to live in accordance with his will, and any other use of the Torah is a desecration of that gift. That's all I have to say on the matter.

For the record, I am in favor of controlled immigration, provided that the immigrants learn English, work hard, and support the guiding principles of the American Constitution. As far as I'm concerned, most of the legal immigrants we get fit that bill.
