Thanks for your question. I will try to help.
If you do not have access to significant funds for investment, are not married/in a relationship with a UK national/foreign national or person with ILR then he would probably have to see if he can apply for a Tier 2 Sponsored Skilled Worker visa
This means that you would be looking at applying under the Tier 2 Sponsored Skilled Workers Visa provisions. You will have to see if the job that he would do for you is on the shortage occupation list:-
If your job is not on this list then this means that you would have to carry out a Resident Labour Market Test. This test is effectively to show that their are no resident/eea national in the locality that can perform your role, It makes it much more difficult to prove that there is no-one else in the Uk who could do the job.
You would then have to become a licensed sponsor of Tier 2 employes:
Then you would have to offer him a job and he could then only apply if he meets the eligibility criteria:
Basiccally, if you are minded to try and become and sponsor and then for him to apply I would strongly consider instructing a solicitor to act on your behalf to review the likelihood of success in detail and then to act on his behalf.
My goal is to provide you with a good service. If you feel you have received anything less, please reply back. Please remember to leave positive feedback using the stars at the top of the page.
There are different types of tier 5 visa.
Which were you told he may be eligible for?
I will answer at 9am
The tier 5 visas are as follows:
So, as I originally said, it would appear to be Tier 2 general or no visa I'm afraid.
I am sorry I could not have better news for you but I would be grateful if you would please leave positive feedback based on the accuracy and content of my answer.Tom
