Most applications are decided within 6 months but many are much quicker. The exact time will depend on which immigration category you are applying under and whether you are making your application from in or outside of the UK.
We will endeavour to submit your application promptly, once we have received your full instructions and all of the necessary information and supporting documentation.
If you are in a particular hurry, for an additional fee, it may be possible to receive a priority service. For applications made from within the UK, this could be as quickly as the next working day (super priority service) or within 5 working days (priority service).
