Kseniia Petrova has been in the united States on a J-1 fellow visa since May 2023,working at Harvard University. Her lawyer, Gregory Romanovsky, indicated that Petrova faces possible deportation to Russia, where she fears imprisonment for protesting against the invasion of Ukraine.
on Feb. 16, Petrova returned from France to Boston Logan airport after a work trip and went through immigration without problems. Though, while waiting for luggage, two Customs and Border Protection (CBP) agents led her to a room to inspect the luggage and registered her phone, according to the lawyer.
Agents found a sample of frog embryos related to the scientist’s research.

According to Romanovsky, Thay found a scientific sample of frog embryos that she brought at the request of her principal researcher, her professor at Harvard, from the France laboratory with whom they collaborate. She carried them in her luggage and did not declare it. She had no previous experience in the transport of samples. She did not think well.She did not review the rules. It was her fault.
romanovsky explained that the CBP usually imposes two sanctions for typical customs infractions: confiscation of the item and a fine of about $500.
They did not. Rather, they decided to punish her by annulling her visa,
Romanovsky said. It was then that hell unleashed. They said: ‘Kseniia, we are going to cancel the visa. We will ride you again on the plane to Paris.’
According to article 212 of the Immigration and Nationality Law, several reasons can preclude entry to the United states, including issues related to health, criminal records, and terrorism. Romanovsky said that, although the CBP can cancel visas, it needs a reason that justifies it, which he argues was not present in Petrova’s case.
Instead, the agency gave petrova two options.The first was to withdraw her request for admission to the United States and leave voluntarily, with the opportunity to go to an embassy in another country and request a visa to re-enter the country. the second was for the CBP to issue an accelerated expulsion order and put her on a plane back to Paris.However, due to the prohibition of re-entry under an expulsion order, she could not return for at least five years.
Romanovsky said Petrova decided to withdraw her admission application.
According to her lawyer, petrova said, Please, put me again on the plane to France, I’m going to do what they tell me. I’m going to request a visa. I want to do the right thing.
Then, according to Romanovsky, the agents asked, Okay. Do you want us to notify what happened today to the Russian government or the Russian consulate?
Her lawyer pointed out that Petrova told them not to notify the Russian consulate, saying, I can’t go to Russia.There they will chase me.
Petrova has a history of persecution there for her political activity, Romanovsky said. She was arrested in Russia in 2022 for protesting against the war in Ukraine, according to The Harvard Crimson.
Romanovsky stated, she has been arrested there, and her arrest and her activity in social networks will almost surely assure her a good and strong jail sentence, so at that time she said: ‘I cannot return to Russia.’
Petrova’s detention occurs amid increased scrutiny of foreign students, including visa revocations. While some revocations have been linked to activism related to the conflict between Israel and Hamas, Petrova’s case appears unique, as her activism is related to opposition to the Russian war in Ukraine.
Romanovsky said that the CBP then followed what is called a credible fear process, in which non-citizens can claim that they have a credible fear of persecution or torture and request asylum in the united States. In that case, the person who presents their case is questioned before an immigration judge.
This is where she is right now as she has proven to have a credible fear,
added the lawyer.
She is now waiting for a hearing before an immigration judge in Jena, Louisiana, set for May 7.
Though, even though the immigration judge grants asylum, the government can appeal and continue to keep her detained.
I would love to say that she will know what to expect in a couple of months, and that she will be released if they approve it, but we do not know,
Romanovsky added.
At the same time, Romanovsky said, they have a pending demand against the Department of homeland Security (DHS) and the CBP in the Vermont district, where she was detained before being transferred to Louisiana. The demand hearing, in which the undue revocation of the visa and her initial arrest are alleged, is scheduled for June 9.
Romanovsky advocates for Petrova’s release while waiting for her hearing in Immigration Court.
She is undoubtedly a victim of the new indiscriminate detention policy, which retains people and does not release them, without taking into account if they represent a threat to someone or if there is a risk of escape,
Romanovsky said. It really makes no sense to continue retaining her; it is only occupying space. she is not a danger to the community. She is not a risk of escape.
The lawyer described Petrova as a brilliant scientist
and a person very, very sweet. She is a very good friend and a person very trustworthy, reliable, and friendly.
romanovsky added that Petrova’s principal investigator at Harvard asked the lawyer to provide letters from Nobel laureates in support of Kseniia.
Harvard confirmed in a statement that she is an associated researcher at Harvard Medical School: we are monitoring this situation.
The DHS did not promptly respond to requests for comment.
Researcher Detained After Visa Revoked Over Frog Samples: What You Need to Know
In a case that has raised concerns about immigration policies and the treatment of foreign researchers, Kseniia Petrova, a Russian medical researcher affiliated with Harvard university, was detained by U.S. Customs and Border Protection (CBP) after her visa was revoked. This article provides a comprehensive overview of the situation, addressing key questions and concerns.
What happened to Kseniia Petrova?
Kseniia Petrova, a researcher at Harvard Medical School, was detained at an immigration facility in Louisiana. Her J-1 fellow visa was revoked last month. According to her lawyer,Gregory Romanovsky,the revocation followed the discovery of undeclared frog samples in her luggage at Boston Logan Airport.
On Febuary 16th, 2025, Petrova returned from a work trip in France and was stopped by CBP agents. During a luggage inspection, agents found frog embryos related to her research. Petrova did not declare these samples,which led to the visa revocation.
Why Was Her Visa Revoked?
According to her lawyer, the visa revocation stemmed from the undeclared frog samples. Romanovsky stated that Petrova was carrying the samples at the request of her professor, but failed to declare them. CBP typically imposes a fine and confiscation for such infractions, but in this case, they revoked her visa.
What are the potential consequences for Petrova?
- Deportation to Russia: petrova faces possible deportation to Russia.
- Fear of Imprisonment: She fears imprisonment in Russia due to her past protesting against the invasion of Ukraine.
What is the “Credible Fear” Process?
Becuase she may be persecuted in her home contry, Petrova is in the “credible fear process,” where non-citizens can claim a credible fear of persecution or torture and request asylum.
What are the next steps in the case?
- Immigration Court Hearing: Petrova is awaiting a hearing before an immigration judge in Jena, Louisiana, scheduled for May 7th.
- Potential Deportation: Even if asylum is granted,the government can appeal,perhaps leading to her continued detention.
- Pending Demand: A pending demand is against the Department of Homeland Security (DHS) and the CBP in Vermont. The hearing is scheduled for June 9th. The demand alleges undue revocation of the visa and her initial arrest.
What is the Significance of This case?
petrova’s case highlights several critically important issues:
- Increased scrutiny of foreign students and researchers,including visa revocations.
- Concerns about the detention of individuals who do not pose a threat to the community or risk of escape.
- the potential for political persecution faced by individuals who oppose the Russian government.

What is Harvard’s Response?
Harvard University has confirmed that Kseniia Petrova is an associated researcher at Harvard Medical School. They have stated that they are monitoring the situation.
What are the Legal Arguments?
Romanovsky argues that the CBP did not have sufficient reason to revoke Petrova’s visa. According to Article 212 of the Immigration and Nationality Law, there must be a valid reason for denying entry to the United States. Romanovsky believes that this was not present in Petrova’s case.
Conclusion
The case of Kseniia Petrova raises complex questions about immigration law, international relations, and the protection of researchers. As the legal process continues, the outcome will have meaningful implications for Petrova and could set a precedent for how similar cases are handled in the future.
