Key Takeaways
• Federal judge granted ICE bail to Harvard researcher Kseniia Petrova on May 28, 2025.
• Petrova faces criminal smuggling charges and remains in U.S. Marshals custody in Louisiana.
• Judge found Petrova’s detention unlawful; frog embryos were non-living and posed no danger.
A federal judge in Vermont has granted bail to a Harvard researcher held by U.S. Immigration and Customs Enforcement (ICE), but the scientist remains in custody on separate criminal charges. The case, which centers on the alleged smuggling of frog embryos into the United States 🇺🇸, raises important questions about immigration enforcement, scientific research, and the legal rights of foreign scholars working in the country. Here’s a detailed look at what happened, why it matters, and what comes next for the researcher, the government, and the broader academic community.
Who is Involved and What Happened?
On May 28, 2025, U.S. District Judge Christina Reiss ruled that Kseniia Petrova, a 30-year-old Russian-born researcher at Harvard University, should be released from immigration detention. Petrova had been held by ICE since February 2025, after being stopped at Boston Logan International Airport. Customs officials questioned her about frog embryo samples she brought from a French laboratory. Petrova said she did not know she needed to declare the samples and denied trying to smuggle them.
Despite the judge’s decision to grant ICE bail, Petrova remains in custody under the U.S. Marshals Service in Louisiana. This is because she now faces criminal charges related to the alleged smuggling. She is expected to be moved to Massachusetts 🇺🇸 for a separate bail hearing on the criminal case.
Why Was Petrova Detained?
Petrova’s troubles began when she returned to the United States 🇺🇸 from a vacation in France. At the airport, U.S. Customs and Border Protection (CBP) officers inspected her luggage and found frog embryo samples. These samples came from a French lab known for working with very thin sections of frog embryos, which are used in advanced biological research.
Petrova told The Associated Press that she did not realize the samples needed to be declared. She said she was not trying to hide anything or break the law. However, CBP officers canceled her visa and handed her over to ICE, who then detained her.
Key Points from the Judge’s Ruling
Judge Reiss’s decision to grant ICE bail was based on several important findings:
- Unlawful Detention: The judge found that immigration officers did not have a legal reason to detain Petrova.
- No Danger to the Community: The court determined that Petrova does not pose a threat to public safety.
- Nature of the Embryos: The frog embryos were non-living and non-hazardous, meaning they did not pose any risk to people or the environment.
The judge gave the government until Friday, May 30, 2025, to suggest terms for Petrova’s release. However, because of the new criminal charges, Petrova remains in custody under a different authority.
Legal Arguments: Both Sides of the Story
Petrova’s lawyer, Gregory Romanovsky, argued that CBP had no legal basis to cancel her visa or detain her. He said there was “clear and convincing evidence” that Petrova was not carrying anything dangerous or illegal. Romanovsky also claimed that customs officers at Logan International Airport acted outside their authority.
On the other hand, the Department of Homeland Security (DHS) said on social media that Petrova lied to federal officers about what she was carrying. DHS also claimed that messages found on her phone showed she planned to bring the materials into the country without declaring them.
Romanovsky asked the judge to prevent ICE from detaining Petrova again if she is released from criminal custody in Massachusetts. Judge Reiss declined to issue such an order, saying she could not stop an executive agency from taking future actions that are not certain. However, a Department of Justice attorney said the government does not plan to re-arrest Petrova at this time.
Professional Background: Who is Kseniia Petrova?
Petrova is a respected researcher at Harvard University, working on projects that could help develop new cancer treatments. During the court hearing, several scientists and academics spoke in her favor. Michael West, a well-known scientist and entrepreneur in the biotech field, praised Petrova’s research, calling it “excellent science.” He explained that her work on embryonic development could lead to new ways to treat aging and disease.
West said he would hire Petrova “in a heartbeat,” showing how valuable her skills are to the scientific community. This support highlights the potential impact of her work and the importance of allowing talented researchers to continue their studies in the United States 🇺🇸.
Harvard University has released a statement saying it is “monitoring the situation,” but has not commented further.
How Does ICE Bail Work?
When someone is detained by ICE, they may be eligible for release on bail (also called a bond). This means the person can leave detention while their immigration case is being decided, as long as they follow certain rules. The judge decides if the person is a flight risk (likely to run away) or a danger to the community. In Petrova’s case, the judge found she was neither.

What Happens Next?
Petrova is expected to be moved to Massachusetts 🇺🇸 by Friday, May 30, 2025, for a bail hearing on the criminal charges. This hearing will decide if she can be released while waiting for her criminal trial. The outcome of both the immigration and criminal cases will affect her future in the United States 🇺🇸, her research career, and possibly her ability to stay in the country.

ICE Bail and Criminal Custody: What’s the Difference?
It’s important to understand the difference between ICE bail and criminal custody. ICE bail allows someone to be released from immigration detention, but if there are criminal charges, the person can still be held by the U.S. Marshals Service or local law enforcement. In Petrova’s case, even though the federal judge granted her ICE bail, she remains in custody because of the criminal smuggling charges.
What is Smuggling in This Context?
Smuggling usually means bringing goods into a country without following the law. In this case, the government says Petrova tried to bring frog embryo samples into the United States 🇺🇸 without declaring them. Petrova says she did not know she needed to declare the samples and did not try to hide them.
What Are the Legal Rights of Foreign Researchers?
Foreign researchers in the United States 🇺🇸 have the right to due process, which means fair treatment under the law. They can have a lawyer, present evidence, and challenge the government’s actions in court. However, immigration law is complex, and even small mistakes can lead to serious consequences, such as visa cancellation or detention.
How Can Researchers Protect Themselves?
- Know the Rules: Always check what items need to be declared when entering the United States 🇺🇸. This includes biological samples, chemicals, and research materials.
- Ask for Help: If you are unsure, ask your university’s international office or legal team for advice before traveling.
- Keep Records: Have clear documentation about your research materials and why you are carrying them.
- Legal Support: If you are detained, ask for a lawyer and do not sign anything you do not understand.
What Does This Mean for the Future?
The outcome of Petrova’s case could have a big impact on how scientific research is done across borders. If researchers fear legal trouble for carrying samples, it could slow down important work in medicine and science. At the same time, the government wants to make sure that dangerous or illegal items do not enter the country.
As reported by VisaVerge.com, cases like Petrova’s highlight the need for clear rules and better communication between scientists, universities, and government agencies. This can help prevent misunderstandings and protect both public safety and scientific progress.
