Hello, I am currently in Thailand from the UK and arrived on the 15th of March, I was given a 30 day tourist visa on arrival and I was planning on extending my visa here, I plan to fly home on 23rd April. I have made a big mistake and left it last minute and realised because of the holidays most immigration offices will be shut. My visa will end on the 13th of April. I have looked at flights out of the country but they are all quite expensive so I’m wondering would I be able to go to the immigration office as soon as it opens up again and apply for an extension and pay the fine for the amount of days I have overstayed? And will it cause me problems in the future when visiting other countries? Any advice will be appreciated, thank you.
