Hey guys,
I applied for a new British passport a few weeks ago because my current one is almost full.
Got an email telling me it's ready for pickup but I won't be heading to Bangkok until next month. They said that's cool, we'll hold onto it.
My question is: Can I extend the Tourist Visa in my current passport or will it flag on their system as void or something?
Really hoping I don't have to do an emergency trip to Bangkok. :)
