BLUE PEN SIGNATURE

Did a search on this here and it has been mentioned a few times, but today at Chiang Mai immigration it became clear as a matter of policy. Always sign documents with a *blue pen* or else they will be rejected. Apparently black ink signatures may be suspect of being "copies" or "fakes" but showing the blue ink is deemed a mark of authenticity. Note, this applies to *signatures* but not fill-in-the-blank text. So make a note of it - in blue. ✒️💙👍
