Does Thailand need a blank passport page?
US passport, fly 6 Sep. One nearly-full book. I do not want a blog’s “they never look.”
What missions actually write
| Check | Treat as | Source shape (as of 30 Aug 2026) |
|---|---|---|
| Blank page | UK FCDO wants at least one. Other missions often rhyme | Confirm your embassy, not a US Facebook group |
| Validity | FCDO: six months after arrival | Same page. Airlines can be stricter than the desk |
| Stamps already messy | A second passport / renewal before you fly | A full book is not a personality |
| TDAC / exemption | Separate products | TDAC does not add a page |
This is not legal advice. A page and a date. Photo of the last stamps if it is tight.
