UK Visas and Immigration publishes service standards for each route and location, and offers priority services at additional cost. Those published times are the only figures worth planning against - and they change, so check gov.uk for your route before you commit to a start date.
What this article can give you is the shape of the wait and the parts you can influence.
The clock does not start when you decide to move
By the time the visa application is submitted, you have already spent months on the stages before it:
- Job search and offer - usually the longest stage by far.
- Certificate of Sponsorship assignment by the employer.
- Document gathering: passport, qualifications, English test, maintenance evidence where required, TB test certificate where required.
Only then does processing begin.
What makes processing slower
- Incomplete or inconsistent documents. The single most common cause of delay.
- Additional checks, which some applications attract.
- Peak season. Late summer is heavy across visa categories.
- Standard rather than priority service - the difference can be substantial.
What you can do
- Get the documents right first time. Names must match exactly across passport, certificates and application; translations must be certified where required.
- Book biometrics promptly - appointment availability is often the hidden delay.
- Consider priority processing if a start date depends on it, and factor the cost in.
- Do not resign until your visa is granted. This is the mistake with the worst consequences - see what happens if a UK job offer falls through after you resign.
Planning advice
Tell your employer a realistic date, not an optimistic one. Employers are generally patient about published processing times and much less patient about a start date that slips twice.
