LPN transition from Puerto Rico to U.S. (I need info)?

In most cities there are hospitals that would love to have your uncle work for them. Some will help you over come any transition problems. I think there is reciprocity with Puerto Rico. Pick a city he would like to live in and contact the hospitals in the area. Salaries and benefits are generally good. Two problems. His English must be good to very good and he will lose his 15 years towards benefits the new hospital might pay.
