Your old friend Bert Donaldsson sends you a message asking if he can call you tonight at 20$20$:00,$00,$ it is very important and since he heard that you have completed a course in international human resource management, he wants to ask you for advice. He tells you briefly about his experiences and that he has now made the decision to leave Argos International in Switzerland and prefers to return home to the United States to work for the same company. He has not yet informed his superiors of this decision. He has heard that moving back home is a big challenge or that the so−$-$called "repatriation" can be difficult, so he really needs professional help. You answer the message and tell him to definitely call tonight and at the same time

What advice would you give Bert about returning home?
