After 5 years its simply a case of renewal.. From memory it was a just over a 100 Quid for the visa. It was the medical that cost me the most as my UK doctor charged me 100 Pounds for the medical plus extra for blood tests etc..The NHS charged me 100.00 Quid for an ex ray and the Police 25 quid for police clearance which took 3 months!! Plus time off work to attend quick interview with the Embassy Consul.. He said that in his experience an applicant had never been refused!! As I said..contact the R.P embassy as I heard that some things have changed since then...You may not even need a medical now..
