I've read a passport is invalid if
- pages torn
- pages ripped out
- identity unreadable
- stamps unreadable
- passport substantially damaged
Now my passport got a minor water damage with one of the stamps bleeding through (see below). It is a Polish passport, and I'm already traveling.
Is my passport invalid? Do I have to expect issues at the border, especially for south east asian countries like Laos and Indonesia. Any experience on that?
