My sponsor’s job offer has been withdrawn – can I still qualify for a visa?
Under the current rules, no. If you and your sponsor are relocating together, your sponsor will need a UK job offer on which to rely (unless you can qualify via other means, such as relying on cash savings). Unless UKVI issues new guidance, it is most likely that a visa application which does not meet the written requirements will fail. If the job offer is withdrawn after your visa is issued, this is less of a problem. The visa remains valid, but note that to extend you and your sponsor will need to meet the financial requirements at the time of your next application.
