Hi, I am trying to get a medical certificate so that I can apply to exchange my UK driving licence for a Portuguese licence. I received my residency permit and I have registered with my local health centre where I was told I would be contacted by them once they have my SNS number. As there is a timescale for applying to exchange my licence I went to a private clinic to obtain the required medical certificate for the IMT application but the medical centre said they could not issue the certificate until I had my SNS number. I went back to the health centre but they said I had to wait until my registration card was issued and they were unable to tell me how long it would take. Does anyone know of how I can contact, whoever issues the SNS numbers, to try to find out the timeline and also, is it the norm that a private clinic cannot issue a medical certificate for a driving licence without this SNS number or is it perhaps just this particular clinic? Any help in this matter would be very much appreciated.
