The United States is moving to restrict birthright citizenship, which could change one of the core features of American nationality law. The proposal would narrow automatic citizenship for children born in the U.S. and could affect tourists, temporary visa holders, and other non-permanent residents who previously relied on U.S. birth as a pathway to citizenship for their children.
Birthright citizenship in the United States is rooted in the 14th Amendment, adopted in 1868. The key clause grants citizenship to people born in the United States and “subject to the jurisdiction thereof.” The traditional interpretation has been that almost everyone born on U.S. soil becomes a U.S. citizen, with exceptions such as children of foreign diplomats or invading armies.
That principle is known as jus soli, or citizenship by soil. It differs from jus sanguinis, or citizenship by blood, which is more common in Europe and many Asian countries.
Two major U.S. Supreme Court cases are discussed as part of the legal background:
- United States v. Wong Kim Ark (1898): upheld citizenship for a person born in the U.S. to immigrant parents.
- Perkins v. Elg (1939): held that a person born in the U.S. to immigrant parents could retain U.S. citizenship even after being raised abroad, provided they returned and assumed the duties of citizenship as an adult.
In practice, long absences from the United States do not normally cancel U.S. citizenship. A person born in the U.S. generally remains a citizen unless they formally renounce it.
What the Trump Proposal Would Change
The proposal described would deny automatic U.S. citizenship to children born in the United States unless at least one parent is a U.S. citizen or a lawful permanent resident, meaning a green card holder.
As stated in the transcript, the intended standard as of February 2025 is that a child born in the U.S. would not automatically become a citizen unless they are the child of:
- A U.S. citizen
- A green card holder
This would affect more than undocumented immigrants. It could also affect children born to people legally present in the United States on temporary visas, including:
- Tourist visas
- ESTA travel authorization
- Student visas
- H-1B work visas
- O-1 exceptional talent visas
- E-2 investor visas
- Other non-immigrant visa categories
This is important because not everyone legally living in the United States has permanent residence. Many people live, study, work, invest, or operate businesses in the U.S. through non-immigrant visa categories without holding a green card.
A green card also creates major tax consequences. Permanent residents are generally tied into the U.S. tax system more deeply than temporary visa holders, and some long-term green card holders may later face exit tax issues.
Birth Tourism and Legal Entry
The transcript notes that it has historically been legal for pregnant visitors to enter the United States on tourist status if they are honest about their plans, can support themselves, and can pay hospital bills.
The practical concern for U.S. border officers has often been whether the visitor will pay the medical costs and avoid becoming a public burden, rather than whether giving birth itself is prohibited.
Under the proposed model, however, birth in the U.S. while on tourist or temporary status may no longer produce U.S. citizenship for the child.
How the U.S. Compares With Other Countries
The United States is not the only country with birthright citizenship. The transcript states that nearly three dozen countries use unrestricted birthright citizenship, with the policy especially common across the Americas.
Countries mentioned as offering birthright citizenship include:
- United States
- Canada
- Mexico
- Costa Rica
- Brazil
- Argentina
- Panama
- St. Kitts and Nevis
- Other countries in the Americas
- Pakistan
- Fiji
Canada has a similar system to the United States and has also seen birth tourism, including cases involving Asian mothers giving birth in Vancouver. The transcript argues that Canada may be more attractive than the U.S. for some families because Canadian citizens receive strong access to the U.S., while Canada does not tax citizens abroad in the same way the U.S. does.
Costa Rica is given as an example where a child born there can become a Costa Rican citizen by birth. Brazil, Argentina, Panama, and several Caribbean countries are also discussed as possible birth citizenship destinations.
The main exceptions in the Americas mentioned are Colombia and Chile, where at least one parent must have some form of permanent residence or qualifying status for the child to acquire citizenship by birth.
Portugal’s Different Model
Portugal is presented as an unusual European case.
Most European countries follow citizenship by blood rather than unrestricted citizenship by birth. Simply giving birth in Germany or most other European countries would not normally give the child an extra passport if neither parent has the required local status.
Portugal is different because if a parent holds a Portuguese residence permit for at least one year, a child born in Portugal may become a Portuguese citizen even if neither parent is Portuguese.
This can make Portugal attractive for families with residence permits, including Golden Visa holders, because the child may acquire Portuguese citizenship at birth in addition to the citizenships inherited from the parents.
Why Some Families Avoid U.S. Birth Citizenship
For wealthy or internationally mobile families, U.S. citizenship can be a liability because the United States taxes citizens on worldwide income.
The transcript gives the example of Boris Johnson, who was born in the United States, left at age five, and later faced a U.S. tax bill after selling his London home. The U.K. did not tax the sale in the same way, but the IRS did because he was still a U.S. citizen. Johnson later renounced U.S. citizenship.
This is one reason the transcript argues that successful families should think carefully before giving a child U.S. citizenship by birth. A U.S. passport may provide opportunity, but it also creates lifelong filing, tax, and compliance obligations unless the person later renounces.
For families that already have strong Western passports, a more neutral or non-U.S. passport may be more useful. The transcript mentions countries such as Brazil, Mexico, Panama, Costa Rica, and St. Kitts and Nevis as possible birth citizenship options, depending on the family’s goals.
Possible Effects on U.S. Competitiveness
Restricting birthright citizenship may make the United States less attractive to some foreign talent.
For example, a skilled worker from India considering the U.S. tech sector may compare the United States with Dubai, Qatar, Singapore, Ireland, or other hubs. If the U.S. offers high taxes, expensive living, immigration backlogs, and no automatic citizenship for children born during temporary legal residence, the overall value proposition may weaken.
The transcript argues that the U.S. may lose some talent at the margin, especially as other countries make it easier for skilled workers, entrepreneurs, and investors to relocate.
Countries mentioned as alternatives for global talent include:
- Dubai
- Qatar
- Singapore
- Ireland
- Other countries with easier relocation frameworks
The point is not that ending birthright citizenship alone will stop migration to the U.S., but that it could reduce one of the benefits that made the U.S. more attractive.
Legal and Constitutional Uncertainty
The policy may face legal challenges because birthright citizenship has long been tied to the 14th Amendment and Supreme Court precedent.
The transcript notes two possible paths:
- A constitutional amendment, which would be difficult
- A Supreme Court ruling accepting a narrower interpretation of the 14th Amendment
The argument behind the proposed restriction is that children of people not permanently subject to U.S. jurisdiction should not automatically become U.S. citizens. The counterargument is that people physically present in the United States, including temporary visa holders, are generally subject to U.S. laws and legal jurisdiction while there.
The policy therefore turns on how “subject to the jurisdiction” is interpreted.
What Families Should Consider
Families planning where to give birth should evaluate citizenship consequences before the child is born.
Key questions include:
- Will the child receive citizenship by birth in that country?
- Will the child also inherit citizenship from the parents?
- Does the new citizenship create tax filing or military obligations?
- Is the passport useful for travel, residence, or future education?
- Does the country tax citizens abroad?
- Does the country welcome birth tourism or restrict it?
- Do parents need residence status before birth?
- Does the child’s citizenship help parents obtain residence?
- Could the country later change the rules?
For families with strong existing passports, U.S. birth citizenship may not be the best default choice. For families from unstable or lower-opportunity countries, a U.S. passport may still be highly valuable. The right answer depends on the parents’ citizenships, wealth level, tax situation, residence plans, and long-term goals.
The practical lesson is that birth citizenship should be planned like any other part of a global mobility strategy. The country of birth can shape a child’s future opportunities, tax exposure, and legal obligations for life.
