Chris Wright has asked us to make members aware of a possible change for those in receipt of the S1 form.
A message from the British Consul for Portugal states:
Please find attached a letter that DHSC has asked me to forward to you. I would be grateful if you could send it on to all your members. If you have any queries about the contents please use the email in Annex 1 which is included in the attached letter.
The letter can be accessed in pdf form by clicking here
Update: It would now appear that only those who have changed details (address etc) since originally registering their S1 need to get in touch with the relevant authorities. If nothing has changed you do not need to re-register. This information is correct as far as we know, but as with most things to do with the authorities it may well change again!
