The visa process has taken Jiajia and I many hours to complete: finding, creating, copying and collating 50-odd pieces of paper required to support her application form. Britain doesn't make it easy for visitors from outside Europe! The actual "handing in" part took just half an hour though, so we had some free time in the city before our onward flights.
We should find out the result of the visa application in 2-3 weeks.
