My passport that was brand new in October has started to look like this on every page. Does anyone know why or whether it will affect me at immigration coming into Thailand?

Looking for advice...

I've got a US passport. 2 years left. 20 pages still good (had an additional set put in a few years back in CM).

I'm considering getting a new passport due to the large number of Cambodian visas, Thai visas, and entry stamps.

Every time I cross, the IO on both sides look a bit sideways and page back and fourth looking for the current stamp.

I want to get a METV in Los Angles this trip.

Anyone have any idea if they look at a 3/4 full and a bit tatty passport negatively when deciding to issue a new Visa?

Is it worth the money and hassle to get a clean slate?

(I do have 2 land visa on arrivals in 2018)

Thanks!
