**US President Donald Trump has announced new executive orders aimed at ending so-called birth tourism in the US and limiting birthright citizenship for certain groups. **

It is part of a renewed effort by his administration to restrict access to US citizenship after the Supreme Court shot down Trump's first attempt in June.

Birthright citizenship refers to the practice of granting citizenship to those born on US soil, with some exceptions, while birth tourism is when foreign nationals come to the US specifically to give birth and get their child citizenship.

Here's what you need to know.

What are Trump's latest executive orders?

Trump signed two executive orders, a written order issued by a president to the federal government which does not require congressional approval, on Thursday.

One expands the existing definitions of non-citizens whose children are not eligible for birthright citizenship.

It prevents the automatic citizenship of babies born in the US to two non-citizen parents if one of the parents is a member of a foreign terrorist group, is a foreign government employee, has attempted to gain citizenship through fraudulent means, or is living in US territories where citizenship is not granted by US federal law.

A few of those categories were already excluded under current birthright citizenship rules, but the one relating to membership of a foreign terrorist group could raise issues, according to Colleen Putzel-Kavanaugh, an associate policy analyst at the Migration Policy Institute, an independent nonpartisan research group.

She said it is difficult to know how, when, and by whom membership would be determined, and it is also not clear "if the onus for proof falls on the government (to prove they are a member) or the individual (to prove they are not)".

The second order, meanwhile, seeks to end the practice of birth tourism by directing the departments of state and homeland security to enhance regulations and expand enforcement against the practice.

It is already illegal to travel to the US for the purpose of giving birth.

According to the executive order, operators in the birth tourism industry use deceptive advertising to entice foreign nationals to give birth in the US.

"They promise citizenship; access to public benefits; and short-term stays in specialised facilities, hotels, or rentals, but often fail to deliver on these promises," the order says.

How does birthright citizenship work?

The principle of birthright citizenship, known in legal terms as "jus soli" or "right of the soil", is enshrined in the 14th Amendment of the US Constitution.

The law was originally meant to grant citizenship to American-born, formerly enslaved people following the American Civil War.

Currently, nearly everyone born in the US, regardless of their parents' citizenship status, is granted US citizenship - with a few exceptions.

These include children born in the US to foreign diplomats, those born to enemy soldiers during a hostile occupation of US territory, and those born in unincorporated US territories where a federal statute has not granted the right to citizenship.

People born in the US territories of Puerto Rico, Guam, and the US Virgin Islands, for example, get automatic citizenship, while those born in unincorporated American Samoa are not and are instead considered "non-citizen nationals".

How many birth tourists are there in the US?

Trump said on Thursday that "hundreds of thousands" of babies have been born through birth tourism in the US, without providing evidence or clarifying if that figure is annual or not.

There are no government figures specifically on women coming to the US on tourism visas to give birth, but there is data on foreign residents giving birth in the country.

These show that just over 9,500 babies were born to foreign women in the US in 2024, according to the most recent estimate, external from the Centers for Disease Control (CDC). This is based on births registered to mothers with foreign addresses.

In comparison, there were 3.7 million US births in total that same year, CDC figures show,, external meaning babies born to foreign US residents amounted to roughly 0.25% of these.

However, the MPI says the government figures are likely an undercount and that foreigners could use a US address that is not their permanent home to register a birth.

The MPI estimates, external that between 20,000 to 26,000 babies were born in the US annually as a result of birth tourism, which is about 0.5 to 0.7% of total annual births.

This figure is based on a wider review of US census data, although their study notes that it is hard to know exact numbers for certain.

"Birth tourism inherently relies on the intent of an individual to come to the US to give birth and capturing that intent in data is difficult," said Putzel-Kavanaugh.

"For some women, they may be travelling and a medical emergency could necessitate birth in the US even if their intent was to give birth back in their home country."

What happened at the Supreme Court?

The Trump administration's argument against birthright citizenship when the case was before the Supreme Court in April relied heavily on the need to end birth tourism.

Solicitor General D John Sauer argued that granting everyone born on US soil citizenship has allowed the birth tourism industry to thrive and created a "whole generation of American citizens abroad with no meaningful ties to the United States".

At one point, Chief Justice John Roberts asked Sauer whether he agreed that birth tourism "has no impact on the legal analysis before us".

Sauer responded that the existence of birth tourism proves that the 14th amendment has unintended consequences that would never have been approved by its creators.

We live in a world now, Sauer said, "where eight billion people are one plane ride away from having a child who's a US citizen".

Roberts, and ultimately the high court's majority, rejected that interpretation, saying: "Well, it's a new world. It's the same Constitution."

Do other countries have birthright citizenship?

Trump has repeatedly said the US is one of the only major countries that grants birthright citizenship.

In fact, more than 30 countries practise automatic "jus soli" and without restriction in almost all cases. They include Brazil, Argentina and Mexico, as well as most other countries in Central and South America.

The US and Canada are the only two countries considered "developed" nations by the International Monetary Fund that grant mostly unrestricted birthright citizenship.

Other countries, like the UK and Australia, allow for a modified version where citizenship is automatically granted if one parent is a citizen or permanent resident.
