I was wondering if it was possible to reapply and get granted a new UK visa immediately after the previous one expired? I've already read a few answers that touch upon this topic and there seemingly is no rule explicitly forbidding this, but I am unsure if this applies to the current circumstances of my colleagues.
The situation is that we have a team or workers completing a project in the UK (for a UK company), which is planned to take 10 months. We've already received 6-month Standard Visitor Visas for our team members and wanted to reapply for new Standard Visitor Visas for them when the previous visas expire so they can complete the project, since they're already well versed in all aspects of the job.
