I am an owner of a small startup in UK and have a small team. I offered an oversea student (his student Tier 4 visa is end on this year Jan) an internship role from last year Sept to Dec.
However, his first 3 months performance is very bad: come to work late and leave early. I don't want to renew his contract, but he promised he would work very hard and he apologies that he cannot focus on the work just because he has some problems with family. He sent an email to say sorry and promise he would work very hard and try his best to contribute to my company.
So I decide to pay the visa agent to sponsor his Tier 5 visa. However, on the early of Jan, after he submitted the visa application, he suddenly refused to work any more on the second day. On our last conversation, he claims that currently he is preparing for applying big company and also applying PhD study. Thus he claims he is too busy to work.
Now, he blocked my phone number, and didn't reply me email or msg. And my other employees told me that they saw this student was preparing the PhD proposal on last year intern. Because this student always pretend to be very nice to colleagues, they don't want to tell me on him at that time.
Is there anyone can tell me what should I do right now? I know I should ask lawyer, but it takes time and expensive, I want to know what can I do currently and what should I prepare? I am not local people and have not clear idea about the law. One of my friend tells me that this is my responsibility that I didn't do a detail check before sponsoring his visa, so I cannot ask home office to pause his visa application and decline him. I am very angry and I don't want to pay him anymore.

I got advices from lawyer, and reported him to UK home office & UK border authority to withdraw his visa. Thanks everyone.
