Business Immigration

From sponsorship licences and renewals to compliance checks and visas applications, we have the experience to help you. Getting these applications wrong can cause significant inconvenience and expense to both the company and the intended migrant. You’ll need someone who understands your situation and the way the rules work to build a credible application or tell it to you straight if yours is a lost cause.

Please note: we don’t take asylum or detention cases and we don’t work under Legal Help. (add helpful link)

You’ll have a range of questions. The sort of questions we are asked include:

  • How does my company get a licence to sponsor a migrant worker?
  • Can our overseas associate company send a couple of sales executives over to help design our global marketing strategy?
  • We urgently need to bring someone in from our Mumbai office for a couple of weeks. Can we do so?
  • We want to appoint a senior executive who’s South African. His wife is Dutch; can we piggy back him on her EU rights without having to get a licence?
  • Can you help our French sub-contractor who has 5 Indian employees with visas to work in France? He wants to bring them to the UK to complete the UK aspects of his project for us.
  • Can we employ a migrant who tells us that although his existing visa has expired, he has applied for a new one and doesn’t know when it will be granted?

Director of Care Services Company re: Kathryn Casey-Evans

I recently used the services of Trethowans in an employment matter and I have no hesitation in recommending them. The quality of their legal advice was first class and, in my opinion, superior to many of the larger firms that I have previously used. Their response to issues was always prompt and pragmatic. The costs of their services were fair and a comprehensive breakdown of their costs accompanied their invoice
