In referring to immigration and international focus, etc. - my UG degree is in Middle Eastern Studies, I speak Arabic, have worked with the population for some time and intend to continue that work as I go into law. It does not have to be immigration hands down, but that is where my past experience has been.
As far as my preference for UCLA - their faculty, specifically one professor of Islamic law, appeals greatly to me. As does the potential for earning a dual degree in their Near Eastern Languages & Cultures department.
If you think that you'll be a long shot but you're attracted to a particular school because of something like you mentioned, you could always have a separate personal statement that's narrowly tailored to that particular school explaining why you'd be a special asset. And you could have a more gen'l PS w/ some of what you have in the tailored one to go to other schools.
