Hi,
Is an immigration officer allowed to stamp you in for a lesser time than what your visa is for? For instance, if they ask you how long you're going to be in Thailand under your 60 day Tourist Visa and you say 45 days, can they stamp you in for only 45 days or will it still be the default 60 days allotted by the Tourist Visa?
Thank you
TLDR : Answer Summary
Yes, an immigration officer can stamp you in for a lesser duration than the maximum allowed by your visa. For example, if you enter Thailand on a 60-day Tourist Visa and inform the officer that you'll stay for only 45 days, they have the authority to stamp your passport for that lesser duration.
