I work as an English teacher in Bangkok and have just changed schools. As my old school cancelled my Non-B, I did a Visa run to the Kanchanaburi/ Burma border last week and now have a standard one month visa on arrival (ending 1 September 2018). My current school will apply for a new Non-B but cannot do this until the results of my police clearance check comes through (should be 1-2 weeks), which means I will most likely have to extend my visa again at the start of next month.
The problem is that I am now very limited on space in my UK passport (down to a couple of half pages + quarter pages) meaning if I do another visa run then I may not have space for the Non-B stamp.
I want to apply for a new UK passport but understand that I will not be able to travel on my current passport during the application process. Seeing as it can take up to a month to receive the new passport then this makes it impractical if I need to leave the country by 1st September.
I would really appreciate any sensible advice anyone may have on how best to handle this situation.
