The Department of State issued draft regulations for the PASS card last week, indicating the intended price for the cards:
The limited-use passport card will be adjudicated to the same standards as a traditional passport book. The rule published today proposes a wallet-sized card that would cost $10 for children and $20 for adults, plus a $25 execution fee.
In other words, the PASS cards will be $45 for children and $35 for adults. This is slightly less expensive than the $50 price that was put forward when the PASS cards were announced in January, but I think it’s still at a price point that will be a deterrent to cross-border travel for a large proportion of people in the northern border states.
