Came in to Bangkok airport today from London l have a TV 60 day visa from Thai embasy in London. IO at the airport stamped me in for 30 days not 60 ......i didn't check at the time how do I rectify this please ?
Do I go back to the airport tomorrow ?.......many thanks in advance
TLDR : Answer Summary
After arriving in Bangkok with a 60-day visa but being stamped in for only 30 days, the recommended course of action is to visit the Immigration Office to have the error corrected. While returning to the airport is one option, local immigration offices may also assist. It's important to ensure the visa number is noted on the TM-6 Arrival/Departure Card next time and to double-check the stamp before leaving the immigration area.
