Thanks for your prompt reply. I cannot find any definite information on- line regarding using an expired passport. The Home office told me I could only go to the Zimbabwe Embassy this morning. So many of the goal posts have changed from April 6th. I will contact the premium service for the biometric card on Tuesday. When I have an idea of the time line, I will write and appeal for more time on the citizenship...they have given me until 22 May. After all the effort and expense I hope it will be worth it.
Thank you for the link, that is clear. I will proceed on those lines after the bank holiday. In the mean time composing a convincing letter to HM for an extension of time. I imagine there are many people whose english certificates fall short of the new guidelines as there was a flood of applications prior to the price rise at the beginning of April. I just need to get to Cape Town asap to see my ailing Dad after 31years, originally starting the process to take a position as RGN with the NHS. Does an ILTR stamp in an expired passport mean I don't presently have a valid work permit?
