A physician born in the U.S. said she received an email from the Department of Homeland Security telling her to leave the country.

Lisa Anderson, a doctor based in Connecticut, said she received the troubling email from the DHS on Friday, NBC Connecticut first reported.

“It is time for you to leave the United States,” the email said.

Anderson, who was born in Pennsylvania, said she has “no idea” how she ended up on the department’s radar.

“The language seemed pretty threatening to whomever it might actually apply to,” Anderson told NBC Connecticut.

The emails have been going out to non-U.S. citizens who entered the country using the CBP One mobile app. It’s part of President Donald Trump’s mass deportation push, which has also targeted people who entered the country legally.

Anderson isn’t the only U.S. citizen to receive the email. Nicole Micheroni, a Massachusetts-born immigration attorney, said she received the same email on Friday.

“Do not attempt to remain in the United States — the federal government will find you,” warns the email, which Micheroni posted to Bluesky.

The email said Micheroni had just seven days to leave the U.S.

“I’ve been here my whole life,” Micheroni told local Boston station WCVB.

A senior DHS official told HuffPost on Monday that Micheroni may have been contacted by mistake because a non-U.S. citizen used her email as their own.

“CBP used the known email addresses of the alien to send notifications. If a non-personal email — such as an American citizen contact — was provided by the alien, notices may have been sent to unintended recipients. CBP is monitoring communications and will address any issues on a case-by-case basis,” the official said.
