CONCORD, N.H. — An immigrant from Brazil who faced deportation and argued that the United States isn’t honoring a 15-year-old agreement allowing him to remain in the country will be allowed to stay for now, according to a federal appeals court ruling Friday.

The 1st Circuit Court of Appeals in Boston said it needed time to review the case of Renato Filippi, 58, of Nashua, New Hampshire, who was scheduled to be removed on Nov. 6. The panel of three judges said it granted the stay “without reaching any jurisdictional issues or the merits of the petition for review.” It did not specify the length of the stay.

“It is unusual because people try to get this sort of thing done every day and rarely does anyone succeed,” said Filippi’s attorney, Robert McDaniel.
