I know Mormons now own a lot of the tourism, lodging and fishing businesses in Alaska, and used to bring in scads of college-age kids from Utah as bus drivers, launch workers, deck hands, etc.  I don't know if that's still true or if foreign workers have assumed those roles.
But the past few years I have noticed a number of younger eastern Europeans Central Europeans and Filipinos working here in all sorts of customer service jobs, from Home Depot to Walmart. 
Koreans, other Asians and Pacific Islanders seem to be working more in small retail, in services, or driving cab here; and the factory ship and shore-based fish processing operations seem to have come to rely on foreign workers and companies far more than they used to:
I guess we will know by summer a year from now  if and what kind of changes
Trump's sporadic  and inconsistent policies will create or change in Alaska for foreign workers, and for potential Alaskan and Lower 48 workers/employable persons up here.
