移民政策大转弯 美国正在重新定义「谁能留下来」

美国是一个移民建立的国家。

多少年来，世界各地的人带着一只皮箱、一个梦想，跨越海洋来到这片土地。他们相信，只要努力工作、遵守法律、教育下一代，就有机会在美国建立新的生活。

但是今天，美国的移民政策正在经歷一次重大转变。

过去，移民政策的焦点主要集中在美墨边境、非法入境与遣返问题；如今，政策影响的范围已经逐渐延伸到合法居留者、国际学生、工作签证持有人，以及準备申请永久居留权的人。

这不再只是「边境问题」，而是可能影响千千万万移民家庭的制度性改变。

绿卡申请方式出现重大变化

美国公民及移民服务局在今年五月宣布新的政策方向：部分目前以临时身分合法居留美国、希望申请永久居留的人，原则上可能需要返回本国，透过领事程序申请移民签证；只有在特殊情况下，才可能获准在美国境内调整身分。

这项改变对许多已经在美国工作、读书、生活甚至建立家庭的人而言，具有非常实际的影响。

过去大家认為，只要合法进入美国、符合资格，就可以一步一步完成身分转换。现在，这条道路正在变得更加严格，也更加复杂。

留学生时代也正在改变

另一个重要变化发生在国际教育领域。

国土安全部今年七月公布最终规则，对 F 类国际学生等非移民身分建立固定的合法停留期限及延期程序。

这意味着国际学生不能再把「合法停留」视為一个相对开放的时间概念，而必须更加注意自己的身分期限、学业进度以及延期申请。

对美国的大学而言，这同样是一个重要讯号。

多年来，世界最优秀的年轻人来到美国读书，其中许多人毕业后进入科技、医疗、工程、金融与研究领域，最后成為美国经济的重要力量。

如果制度变得过於困难，美国是否仍然能够吸引全世界最好的人才？

这是一个值得我们思考的问题。

「公共负担」政策重新受到重视

今年七月，政府也对「Public Charge（公共负担）」政策作出重大调整。

对部分申请永久居留的人而言，个人的经济能力、家庭状况以及是否可能依赖政府公共资源，将再次成為更加重要的审查因素。

因此，今天的移民政策正在传达一个非常清楚的讯息：

来到美国只是第一步，能不能长期留下来，将面临更严格的审查。

签证审查全面收紧

就在今天，美国国务院表示，川普政府任内已撤销超过 175,000 个签证，创下极高纪录。

政府表示，撤销原因包括违反签证规定、犯罪、国家安全问题及移民欺诈等；同时，签证申请的安全背景与社群媒体审查也在加强。

这显示美国移民政策的方向已经非常明确：

从边境到机场，从学生签证到工作签证，从临时居留到永久绿卡，整个移民制度正在进入一个「更严格审查」的新时代。

美国需要安全，也需要人才

任何国家都有权保护自己的边境。

非法入境、犯罪、人口贩运以及移民欺诈，都应该依法处理。

但是我们也不能忘记，美国今天之所以成為世界最强大的国家之一，与一代又一代移民的贡献密不可分。

他们创办公司、建立工厂、开设餐馆、成為医生、教授、工程师和企业家；他们缴税、创造就业，也把下一代培养成美国公民。

因此，真正需要思考的问题，不应该只是：

「我们如何阻止人进来？」

而应该是：

「我们希望什麼样的人来到美国，又如何让愿意守法、工作、投资和贡献的人留下来？」

移民制度需要秩序，边境需要安全。

但是美国同样需要梦想。

当移民政策大转弯之际，我们希望华裔、亚裔以及所有移民家庭更加了解新的法律环境，保护自己的合法身分，也更加积极参与美国社会。

因為移民政策最后讨论的不只是一张签证或一张绿卡。

它真正决定的，是——

下一代的美国，将是一个什麼样的国家。

America Is Redefining Who Can Come — and Who Can Stay

Monday, August 10, 2026

America has always been a nation of immigrants.

For generations, people from every corner of the world have come to this country carrying a suitcase, a dream, and the hope of building a better future. They worked hard, raised families, opened businesses, paid taxes, and became part of the American story.

Today, however, America’s immigration landscape is undergoing a major change.

For many years, the national debate focused primarily on illegal immigration, border security, and deportation. Now the impact of immigration policy is reaching much further. Legal immigrants, international students, temporary workers, visa holders, and applicants for permanent residency are all facing a more complicated and uncertain environment.

This is no longer simply a border issue.

It is becoming a question about the future direction of America.

A New Era of Immigration Enforcement

The message coming from Washington is increasingly clear: immigration enforcement and screening are becoming stricter.

The government is placing greater emphasis on immigration status, visa compliance, security reviews, and enforcement of existing laws.

For millions of immigrant families, even a small policy change can have enormous consequences.

Immigration is not simply paperwork.

Behind every visa is a person.

Behind every green card is a family.

Behind every immigration application is often a dream that has taken years to build.

International Students Face New Challenges

America’s international students are also entering a new environment.

For decades, American colleges and universities have attracted some of the brightest young people in the world. They came to study science, engineering, medicine, artificial intelligence, finance, and business.

Many stayed and became researchers, doctors, engineers, entrepreneurs, and business leaders.

They helped create companies, technologies, and jobs.

If America makes it increasingly difficult for talented young people to study, work, and build their futures here, we must ask an important question:

Will the world’s best talent continue to choose America?

The United States is no longer competing only for investment and markets.

We are also competing for people.

America Needs Security — But It Also Needs Talent

Every nation has the right and responsibility to protect its borders.

Illegal immigration, human trafficking, immigration fraud, and serious criminal activity must be addressed according to law.

But enforcement alone cannot define America’s immigration future.

We should remember a fundamental truth:

Immigrants helped build America.

They built railroads and factories.

They opened restaurants, stores, newspapers, banks, and technology companies.

They became doctors, professors, scientists, engineers, journalists, and entrepreneurs.

They created jobs, paid taxes, strengthened communities, and raised generations of Americans.

Therefore, the immigration debate should not simply ask:

“How do we keep people out?”

We should also ask:

“How do we attract and keep the people who will help America succeed?”

The American Dream Must Continue

America needs secure borders.

America needs laws that are respected.

America needs an orderly and fair immigration system.

But America also needs talent.

America needs investment.

America needs innovation.

And America still needs dreamers.

As immigration policy takes a major turn, immigrant communities must understand the changing rules, protect their legal status, and become more involved in American civic life.

The decisions being made today will reach far beyond the border.

They will affect our universities, our businesses, our workforce, our economy, and millions of families.

Ultimately, immigration policy is about much more than a visa, a passport, or a green card.

It is about people.

It is about opportunity.

It is about the American Dream.

And most importantly, it is about one question:

What Kind of America Will We Leave to the Next Generati
