How do countries around the world compete for talents?

Countries around the world mainly adopt the following means when competing for talents. First, the migration of talents. All countries in the world generally regard talent migration as a very key means, and many countries have immigration offices. New Zealand said that immigration should not be regarded as a means to supplement the population, but as a means to attract talents. Some European countries have revised the legal system of immigration naturalization, Germany implemented the talent green card project in 2000, and Britain and France are also adopting these talent policies. Second, dual nationality. Since 1990s, there has been a trend in the world: most developing countries have opened up dual nationality. For example, India, Philippines, Brazil, Mexico, South Korea, Vietnam, Russia and so on. The main purpose of this is to attract local talents to return to China. Adopting dual nationality can turn brain drain into talent enjoyment, which is actually a policy that can attract a large number of talents back without spending a penny. Third, relax the visa. Many countries regard temporary visas as an important means to attract talents. For example, there are three special entry programs for talents in the United States, and there is also a high-tech talent entry program. Under the influence of these projects, an average of more than 200,000 people come to the United States every year. Fourth, adopt the national headhunting method. In the talent war, many talent flows are completed by headhunting companies. For example, after World War II, the United States sent the famous Also commando to hunt and kill German scientists for American citizenship. In order to attract overseas talents, Singapore has set up eight liaison offices overseas to recruit overseas talents. Fifth, the establishment of overseas talent co-ordination institutions and non-governmental organizations to attract talents to return. In addition to headhunting, associations, networks, chambers of commerce, international talent information banks and talent exchange markets should be established to strengthen this work. India has a database of overseas experts, which needs experts in any field to explore. Sixth, set up research and development institutions. Many people didn't come back from abroad because many domestic conditions couldn't meet their research needs. As long as the conditions are met and there are good academic leaders, a large number of talents can be condensed by using the centripetal force of academic leaders.
