Ms. Hunter learned on Friday that the flight had turned around and her clients’ deportations had been rescheduled, though it was unclear for when. An ICE spokeswoman said the agency does not provide that information in advance.

Ms. Hunter said she also had no advance notice when immigration officials recently transported five of her clients from their Minnesota homes. (They were first taken to Louisiana to prepare for their deportation.) Her law firm scrambled to secure stays of removal for the men and helped three avoid the flight.

Now that the other two have had their deportations delayed, Ms. Hunter said she would keep working to prevent their removal. Neither client has a criminal record, and both have been in the United States for more than a decade. One is married to a permanent resident and has children who are United States citizens.

“We’re inclined to think that this sort of failed flight reflects on the fact that more deportations are being carried out in haste and are perhaps not as well-planned as they might have been previously,” she added.

One Somali woman in Minnesota, who did not want to give her name for fear of getting her family in trouble with the authorities, said in a phone interview on Friday that her cousin was among those on the flight.

She said she had been desperate for answers since Wednesday, when her cousin called from Louisiana saying he was about to be deported. “I was very sad. I cried, and he told me not to make him cry,” she said, adding that it would be dangerous for him to land in Mogadishu because he had no connections there. “He hasn’t seen Somalia for the last 20 years.”
