US President Donald Trump's administration refused to temporarily forgive Russia by Ksenia Petrova, who worked at Harvard Medical School. About this Write Bloomberg.

According to the agency, the Immigration and Customs (ICE) stopped Petrov on February 16 at Boston Logan airport due to the fact that the scientist did not introduce frogs to the country from France as part of her research.
Ice employees gave her a choice: returning to France and reuse of visas or deportation to Russia and losing the right to the United States for five years.
Petrova has chosen the first option. She explained by her decision by fearing political persecution in his homeland (in 2022, she was detained in Russia for participating in protests against war in Ukraine).
After that, the service decided to detain it, lawyer Grigory Romanovsky said. A meeting of the migration court in her case was planned on May 7. The scientist applied for UDO request before the hearing, but he was rejected.
ICE stipulates that Petrova does not provide evidence that she does not represent the dangers of Muslims to the United States society or security and will not escape.
In addition, when making a decision to refuse, this service took into account evidence of the past criminal activities of the Russians and the activities of Muslims contradicting the interests of the US National Security, the law enforcement staff explained.
