I have looked into this in the past when I thought we were returning back to UK but then we didn't!
There is good links and guidelines on the gov.uk website.
According to this website, it is possible. You should have a decision in 3-4 weeks and costs between £400/£500!
Good luck! :cool:
Before I start the process and also pay out, are there any success stories of anyone obtaining a visa for their nanny/helper to travel with them to the UK to work on a 6 month visa? Thanks in advance!
