As the global trade has been booming in the past decades, the immigration problem gradually catches the attention internationally, as it is concerned with intangible culture identity and specific impact on the indigenous market.. Under the background of global trade, two trends of international immigration have become the mainstream. Diligent and skilled elite migrate from the developing countries into the first developed countries, along with the illiterate and poor-skilled people, both in pursuit of better improvement.

The low-end industries move out from rich countries into those countries with relatively large labor force and cheap production cost. Either trend causes an unwelcome impact on the indigenous job market, along with the culture conflict, largely explaining the immigration restrictions. However, to lift the restrictions on immigration is of great significance to either the development of the country or the welfare of the human.

Global trade provides a great platform for capital to seek appropriate labor force or other production factors. If the government, probably under the pressure of the industry union, aiming at the protection for indigenous workers, it hinders the incentives on the production due to the resources integration under the hand of the intangible market. Such restrictions can provide temporary shelter for present workers but obviously abates its competitiveness in the future. Even though that secret immigration or sneakers, such as Mexican people moving across the American border, may justify the restrictions considering the instability or surging criminal rate, it should allow greater freedom for those who pursue a better life in a legal way, for example, due to job or education.

Immigration can also relieve population stress and bring new development opportunities to third-level countries, partly explaining the United Nation’s call for the European countries to relax their immigration restrictions. Those immigrants can bring the latest technical development information, efficient entrepreneurial managing system and other more advanced concepts, adding an accelerator to the home country’s development.

From the nature of knowledge, it needs communication, clash and innovation to complete its progress. It is no longer about narrow national prejudice, deeming it as the process of the poor countries stealing technology from them, but a broader sense of global communication and collaboration. Even though globalization can bring culture shock, it can also provide us a chance of investigating our tradition and embracing a more humane and reasonable concept by self-scrutiny and comparison.

The present century poses a promising prospect for human beings. The world is gradually becoming a village under the impact of global trade and the internet. The traditional sense of national border is weakening. It takes great courage to embrace the opportunities, transcends the narrow prejudice, and takes the challenges.
