i have just been in touch with the UK embassy in Ankara, they were about as much help as a chocolate teapot, they did not have a clue what i was going on about, just out of interest fees for the other way round, 6 months single or multi entrance visa 68pound,2years 230pound,5 years 420 pound,10 years 610pound, i get the feeling they love the tourist here, but do not want you here on a permanent basis, unless you pay a ridiculous amount of money for a little blue book,(which you pay for anyway)sad but true iMO.
