The United States is not properly following national laws already on the books as it pertains to green card holders, international students and those with H-1B visas, according to multiple immigration attorneys who spoke with Newsweek.

The Trump administration, following the directive of a president who made immigration arguably his biggest issue on the campaign trail, is overhauling border protocols…

“The revocation of green cards and arrest and detention of individuals in the U.S. without giving them an opportunity to prove their lawful status is a violation of due process,” Seattle-based immigration attorney Kripa Upadhyay told Newsweek.

She said that cardholders are arriving at U.S. ports of entry, including airports and border crossings, and not being provided such rights. She alluded to reports of returning green card holders who have been tricked or pressured into “voluntarily” abandoning their status.

“What the border officers cannot do is then put these individuals in a position where they are so tired of being held in custody for 8-10 hours (often after long haul flights of 16 hours or so) and tell them they can voluntarily choose to relinquish their Lawful Permanent Resident status,” Upadhyay added.

“A LPR’s status can only be revoked by an immigration judge, unless the individual voluntarily relinquishes it. What is happening at the airports/land borders is not voluntary. It is coercion, as was the case of [Schmidt].”
