I applied for Subject Access Request as I had a minor immigration problem with the officer before the last time I entered the Uk. They speculated that I was trying to live in the UK through frequent successive visits but after almost an hour of questioning they let me in. I am applying for a tier 4 residency now and I was trying to find out what the officer wrote on the landing card I sent a SAR and this was the response. "I am afraid that further searches of our databases have not identified any landing card entries. I would also like to make you aware that the Home Office border systems hold records of passenger UK entry and exit data only via scheduled commercial routes. The accuracy of the information provided is dependent on the quality of data submitted by the carriers. Any errors or omissions in the data provided will need to be raised with the carrier that provided the information."
Does that mean that they lost the landing card and that I have a clean slate as records of that problematic entry is lost?
