ORIGINAL POSTERTLDR : Answer Summary
At Chiang Mai immigration, it is important to sign documents with a blue pen to ensure they are accepted, as black ink may be deemed suspicious and labeled as 'copies' or 'fakes'. Blue ink is recognized as a mark of authenticity and is specifically required for signatures, although this does not apply to fill-in-the-blank text.
