Lansing is an integrated city, and it has significant populations of recently arrived hispanics and asians, as well as people from eastern Europe (many fled before the fall of the USSR, and were located here by a local church-sponsored refugee program). I don't expect the influx to alter the language beyond recognizable English, because:

(1) the groups speak different languages and compete with each other as well as English
(2) English tends to absorb foreign terms in popular use
(3) the numbers of immigrants is still not high enough to reach critical mass. Less than ten percent of the population, I'd guess.
