Can I use a US passport card for entry now? The last thread on this topic said yes but only by boat, not air (that's what it was designed for). But those posts were from 2018. I got the card when I last renewed my passport by then never ended up travelling or using it down there. I'm coming back in a few weeks for the first time since 2014 and am starting to get a little nervous. Too late to cancel plans or expedite a passport book. I've got a "man on the inside" who said he'll check for me on Monday. But I thought the TTOL crew might have a quicker answer. Any info would be appreciated!
