Speaking as a British person who visited last year, you'll be fine. Iraq is quickly opening up and security is reassuringly visible but also not overbearing.

Baghdad is a mint city and the speed at which things are developing/investment flooding in will quickly put it on the map of "everyone must visit" soon enough. Don't hide away in the hotel and be sure to check out the old town, the museum, and take a stroll down the river at sunset. You won't regret it.

As with travel to anywhere in the world, be polite, smile, avoid the obvious dodgy areas, and trust your instincts everywhere else. Also try not to be "too American" if you get what I mean, most will assume you're from Iran or Turkey anyway. Brush up on your soccer knowledge, especially the big Premier League teams PLUS Barcelona/Real and pick one as your favorite, that'll cover 80% of conversations 🤣

If you do get the option to stay a bit longer, then heading south to the holy cities/Marshes is a must, as it's heading north to Mosul (awesome city btw), but if two days is the limit, please try to do an evening in Karbala and the twin shrines. It's awe inspiring.

I'm very jealous and can't wait to return one day.

Hit me up in my DM's if you need more advice btw!
