As a cross-border immigration attorney who regularly works with Canadians living, investing, and building businesses in the United States, I pay close attention to citizenship rules on both sides of the border. A recent change to Canadian law is especially interesting and important for families who live internationally.

As someone born in Canada, later naturalized in the United States, and the parent of children born in Canada, this update is both professionally and personally meaningful.

Canada’s New Citizenship Rule: A Big Win for Future Generations

Effective December 15, 2025Canada amended its long-criticized “first-generation limit” on citizenship by descent.

Before this change, Canadian citizenship could generally be passed on only one generation if the child was born outside Canada, no matter how strong the family’s connection to the country.

What the new rule does:

Under the amended law:

  • A Canadian citizen born abroad may now pass citizenship to their child also born abroad
  • If the Canadian parent lived in Canada for at least 1,095 cumulative days (3 years) before the child’s birth or adoption

This restores citizenship eligibility to families who were previously cut off after just one generation abroad.

A Personal Perspective: Why This Matters to My Family

Because my children were born in Canada, they were always able to pass Canadian citizenship on to their children, regardless of where those children were born.

What has changed, and why this amendment is so important, is what happens after that.

Under the old rule, the chain would have ended there.
My grandchildren, if born outside Canada, would not have been able to pass Canadian citizenship to their children at all.

The new rule changes that

Now:

  • My grandchildren can pass Canadian citizenship to their children
  • As long as the parent (my grandchild) lives in Canada for at least 3 years before that child is born

In other words, Canada has restored a multi-generational pathway, provided each generation maintains a real, physical connection to the country.

That is a thoughtful and forward-looking approach to modern, global families.

The United States: Citizenship by Descent Remains Far More Technical

By contrast, the United States does not impose a formal “generation limit,” but its rules are often much harder to navigate.

U.S. citizenship for children born abroad depends on:

  • Whether one or both parents are U.S. citizens
  • Whether the parents are married
  • Exactly how many years the U.S. citizen parent lived in the U.S.
  • When those years were accumulated

For many families, the most common requirement is:

  • 5 total years of U.S. physical presence
  • At least 2 of those years after age 14

Failing to meet these requirements, even by a small margin, can mean citizenship does not pass automatically, often to the surprise of families who assumed it would.

Canada vs. the U.S.: A Clear Contrast

Canada’s updated rule focuses on connection and continuity.
The U.S. system focuses on technical compliance, which often requires careful legal review.

Why This Matters for Canadian E-2 and Cross-Border Families

Many of our Canadian clients come to the U.S. on E-2 investor visas, build businesses, raise families, and live here for years, sometimes while splitting time between countries.

We are often asked:

  • “Is my child a U.S. citizen at birth?”
  • “Will my child be able to pass citizenship on later?”
  • “Do my years living abroad count?”
  • “What happens if we move back and forth?”

Unlike Canada’s new, clearer framework, U.S. citizenship by descent is not intuitive. It often requires a detailed review of travel history, dates, ages, and status.

The Bottom Line

  • Canada has modernized its citizenship-by-descent rules in a way that supports globally mobile families
  • The U.S. system remains complex and unforgiving of mistakes
  • Cross-border families should plan well in advance, not after a child is born

If you or your children were born outside the United States and believe U.S. citizenship may apply, or if you want to ensure it can pass to the next generation, it’s important to consult with an attorney who understands both Canadian and U.S. citizenship systems.

At Heitz Immigration Law, we regularly advise Canadian-U.S. families on:
