Thursday, I wrapped up another trip to Europe that left me with zero passport stamps. I haven’t gotten any coming home since my Global Entry subscription kicked in five years ago, but I also haven’t picked up any arriving in the European Union since the spring of 2017.

That’s when I started traveling to the EU with an Irish passport. The backstory: As I’ve mentioned here before, my grandmother was born in Ireland, which qualifies me for Irish citizenship–and my parents did the extensive paperwork to secure that so I could work in my dad’s office in Paris in 1991 without getting a work visa.

The passport I got then expired after a few years of my using it only as an ID at bars on St. Patrick’s Day (bouncers were uniformly unimpressed), and I didn’t think further about it until being in Europe in November of 2016.

No, Trump’s election alone didn’t drive me to get a new Irish passport. The dreadful non-EU passport lines I saw at Lisbon’s airport did–on top of the even-worse ones I sweated out in Paris that summer.

Renewing a citizenship document that far out of date took exponentially longer than I expected. The post office somehow lost the certified letter with all the required documents–starting with my birth certificate and Irish foreign birth registration–for a few long weeks, leaving me worried that I’d wind up undocumented in two countries. But that envelope finally made its way to the embassy on Sheridan Circle in D.C., and at the end of April I had a passport in burgundy as well as one in blue.

The time savings since then have been enormous in some places. In Paris and Lisbon, I’ve easily dodged 40-minute waits; at Heathrow last summer, my wife and our daughter got to share this EU-citizenship benefit, avoiding what looked like an hour-plus queue for the “All Passports” desks.

At better-run airports like Barcelona, Brussels, and Munich, this passport has only yielded a few minutes that I could spend in a lounge instead of on a line–plus the robotic experience of having my passport read at an electronic gate instead of by a person–but that’s still quality time. In all cases, my Irish passport has gone unstamped, as per EU policy.

It’s not like I get a choice: I have to use an EU passport when entering and leaving the EU, just as I have to use my American passport when returning to the States.

(Yes, the Feds know about my international alter ego. I stopped by the Global Entry office in the Reagan Building not long after getting this passport to have it added to my file.)

There is, however, one country where I’ve yet to derive any benefit from my Irish passport: Ireland. Shamefully enough, I haven’t been back since Web Summit in 2015, and I should do something about that.
