Advantages to using a host-country national ( a resident of the country where the firm's subsidiary is located) include: they are familiar with the local environment, culture, language, and customs already. They do not need to adapt so they may be productive right away, they are familiar with the local business situation, they may enhance the company's image or "goodwill" if they are in higher management positions, and they are usually less expensive to employ

Parent country national (PCN)- Nationality of employee is the same as that of the headquarters of the multinational firm. e.g. a German employee working at the Chinese subsidiary of Volkswagen .

Host country national (HCN) Nationality of employee is the same as that of the local subsidiary. e.g. a Chinese employee working at the Chinese local branch of Volkswagen.

Combination
Sometimes the level of education in host country is low and bringing an employee from the parent country will be the best. To help the company with some issue.

Lack of qualified local personnel in this case they should hire an PCN.
