国家移民管理局成立伊始，移民政策的制定与逐步完善是移民管理工作的当务之急。一些发达国家在制定移民政策方面已经积累了一定的经验，但仍存在着诸多问题。本文介绍了美国移民政策领域最新的研究成果（Cai and Winters 2017）。该论文运用了美国社会调查数据，发现了之前被严重忽略的经验事实导致的政策盲点：受到政策优待的理工科本科毕业生移民的创业比例显著地低于非理工科毕业的移民，其原始差异达到了3.3个百分点。实证研究显示该差异可以部分地被不同学科的创业者和就业者之间不同的收入机会所解释。我们认为人才引进政策应该倾向于鼓励外来劳动技能的有效利用，而不应该盲目地倡导低价值的创业行为。这一结论对于我国制定相关的移民政策是有参考意义的。
Formulating and developing efficient immigrant policies are current necessities，given the State Immigration Administration of China is newly established. Some developed countries have accumulated more experience in immigrant policy making，but caveats remain. This article introduces a recent immigrant study（Cai and Winters 2017）to narrate this fact. This study uses data from American Community Survey to uncover a policy deficiency caused by an overlooked fact：the self-employment rate of foreign-born STEM college graduates，who benefit from pro-STEM policies，is significantly lower than their non-STEM counterparts. The raw difference is 3.3 percent. The empirical results imply that this difference can be partly explained by the different earning opportunities across college majors and employment types. An efficient immigrant policy should encourage efficient use of skilled labor，rather than advocate low-valued entrepreneurial activities. This conclusion can be generalized for our immigration policies making.
