For almost two decades, Yale Law School has nourished me and my work.
I simply cannot imagine a more congenial and stimulating environment for
serious intellectual engagement than this extraordinary institution. In my
time there, Yale Law School has been energetically, wisely, and lovingly led
by three remarkable deans, Harry Wellington (currently dean of New York
Law School, where he has also generously supported my work), Guido Cal-
abresi, and Tony Kronman. Yale's wonderfully quirky faculty and passion-
ate, peerless students have raised many of the fascinating questions sur-'
rounding immigration, citizenship, human rights, and ethnic diversity that I
have taught, thought, and written about for fifteen years and that I again
take up here.

Many other individuals have joined my Yale colleagues in provoking,
challenging, correcting, and assisting me as I struggled to formulate the
ideas and positions advanced in these essays. I am especially grateful to Ted
Wang and Rogers Smith, the coauthors of Chapters 3 and 9, respectively.
Other intellectual debts have been acknowledged in the original versions of
some of the previously published essays. My editors at Westview Press, Leo
Wiegman and Kristin Milavec, shepherded this manuscript with skill and
grace.

Finally, I wish to dedicate this book to America's citizens, strangers, and
in-betweens--that immense polyglot chorus of erstwhile natives, immi-
grants, and sojourners who continue to enrich the swelling, inspiring, as-
tonishingly complex ensemble of American life.
