I am in the process of trying to submit a SAR (Subject Access Request) to UK Visas and Immigration (UKVI), but, I have read this paragraph:
your signature and the date, within the last 6 months – please note your signature as well as your photo identification is used to verify that the person making the request is entitled to do so
However, I have radically changed my signature since the last time I had to pass through UK Immigration (which is the last record they have on file of me).
Would a DPO (Data Protection Officer) be able to reject my request on the basis that my signature is not at all what they have on file? (My photography is still recognizable from the one on their record though.)
