The cost of appealing immigration decisions could go up by more than 700% under a proposal from the U.S. Department of Justice’s Executive Office for Immigration Review, according to Law 360. The EOIR said that it intends to increase fees for eight separate forms, which currently cost either $100 or $110 to file, depending on the form.

The biggest proposed hike would be for filing a notice of appeal in immigration courts. That fee could go up from $110 to $975, a 786% percent increase, while the same fee for filing a reconsideration motion in the Board of Immigration Appeals could increase by 713% to $895.

“It’s one more brick in an invisible wall that this administration is erecting to keep immigrants from being able to vindicate their rights,” said Hasan Shafiqullah, Attorney-in-Charge of The Legal Aid Society’s Immigration Law Unit.
