I just received my renewal passport and when I signed it, I botched my last name, the last part looks like a big smudge. Is this a problem when going through entry/exit, customs, etc?
No problem there has never been a check of the signature when entering. The data on the passport is only what they have always recorded and read or entered into a database. I have been traveling for 25 years. I am here now. This year was my first time I used a biometric scanner (meaning facial and palm print recognition) to enter Europe with no stamping of the passport or interaction with humans. There were a couple people monitoring the electronic entry.
I’d sign it sooner rather than later just to avoid any issues at check-in or border control. Most officers probably won’t care, but an unsigned passport can technically be considered incomplete in some situations.
Who’s to say that’s not how you sign your name, every time? Smudges sometimes happen. Without seeing the rest of the signature on your passport, and based on your description, it wouldn’t seem to be a problem. Of course, I’m not a border control staffer.
While it might well be ok, I wouldn’t necessarily minimize this as a potential problem. The passport must be signed in blue or black ink to be valid. If a passport suffers significant damage it also will likely be considered invalid. It’s not just whether a border control official personally examines the passport, as airline personnel also will and they need to ensure to their satisfaction that you have valid documentation. And the e readers now in widespread use also may well pick up on a signature issue sending you to manual inspection for a closer look. And you need to have your passport readily accepted as valid every single time you use it, anywhere in the world you go. Getting a new passport would certainly be an expensive hassle but that would be the very safest solution. But that likely depends on how much damage the smudge caused and how legible the signature is (or can be made) despite it, and I can’t offer any more dispositive advice than that.
