My family used to own a home in northern Michigan on Little Traverse Bay. It is a vacation destination where the population grows significantly with the arrival of people who have summer houses or just want a vacation in the area. For years, a number of the larger establishments brought in servers and others in the hospitality industry from Jamaica in particular, because they could not find local staff for the season. I can't remember what the visa type is, but a lot of larger restaurant groups and hotels seem to use it when there are local staffing shortages.
