For anyone applying from the UK, GPs do not have to sign this as it's not an NHS certificate/requirement. My Dr refused point blank to sign despite being registered at the practice for years and I had to go private... Crazy...
I'm on a visa extension of one year from the original one year visa. Therefore I'm here legally until the year extension ends, or as far as I'm aware I leave the country which cancels my 'visa' extension.
Oh you are talking about the thread, the process at immigration, not my original question, got you. Enter country on 30 exempt and proceed to immigration as others have said. Thanks.
