Oh, please. Aside from cities that already have Asian populations, there is no huge influx of Asians. Hispanics, yes--they're making inroads into the smallest towns. But if you live in a rural area, you have to drive a long way to encounter Asians.
Even the Koreans who come here often do so just to have a baby (if they know beforehand it will be a boy), and then they go back home. They do this so the child will be an American citizen and ineligible for the mandatory military service.
