When this EU passport was issued, I was only half-jokingly told that I might want to get a new one if I ever was going to travel to the US due to the kind of afro hair I'm sporting in the picture -- specifically because it covers my whole forehead down to my eyebrows, which can be seen but are definitely overshadowed. I was told this only when they were giving me the passport, no one said anything when I gave them the actual picture. Haven't had any problem with it at the few European, non-EU borders where I used it.
Some years after the fact, I am planning a trip to the US and just remembered this. Should I really be worried about it being rejected at the US border? The passport still has over a year before the expiration date and I'm currently not living in my country, so it would be a hassle to pay a visit to the embassy to get it renewed, while also having to postpone the ESTA application.
I had a look at this US Government guide on passport pictures and it definitely is worrying -- the picture of a guy with a couple of rastas over his forehead in the 'hair section' is deemed unacceptable. (While I understand these are guidelines for US passports.)
Advice on whether I should renew the passport or not?
