Hi all I’m after some advice. Whilst in the U.K. I applied to the Thai Embassy for a multi trip visa, to be totally honest I am not 100% sure why and why I paid the £150, I have an extended holiday to visit fitness street upon arrival I showed immigration my visa which they reviewed then got my passport stamped for departure by 27th September, my multi trip visa expires Jan 2025, but come the 27th September what do I need to do to stay a little longer, thanks.
