Hi my 5 year DTV softpower for health and i have a 12 month health programme. I do not want to do a border run (i am based in Phuket) i just want to go online or visit and immigration office and request the extension instead of using funds to do border hops... ... 180 days expires on 9 February but I need to stay until 12 March before returning the UK for approx. 4 months. how do I go about extending my 180 days to cover the additional 4ish weeks as I understand that I need to apply to stay beyond the initial 180 days ? Thank in advance.
