Actually it boggles my mind how low tech it is to require a physical paper document for international travel in 2020.
My U.S. passport expires in less than 3 months, and for me to renew my passport right now I'd have to mail it in and wait 2-3+ months due to COVID19 staffing reductions. Most countries don't allow you to travel with less than 3 months till expiry on your passport.
So basically I'm trapped in the U.S. now due to this stupid physical document (just arrived back in the U.S. after living abroad so wasn't anticipating this). I despise passports, and hope to live to see the day where we're no longer required to present them.
Of course I'm still privileged to have a U.S. passport, as anyone who speaks to citizens of countries like India already know.
