If you overstay in UK you automatically break/breach Immigration laws. You become classed as an “illegal immigrant”, because you are now staying here illegally (in other words, outside of the terms/agreement of your visa). By law, you should leave this country. If the authorities find/catch you staying here without a legal visa, they will arrest you for breaking/breaching Immigration rules. They also have the powers to deport/remove you back to your country of origin.
You also DO NOT HAVE a legal right to work in this country. If any employer employs you, that employer also automatically starts breaching/breaking Immigration laws by employing an “illegal immigrant” (in other words, a person with no valid permit/visa to work in this country). If the authorities catch/find you working without a legal permit/visa, they will arrest you for breaking/breaching Immigration rules. They also have the powers to deport/remove you back to your country of origin.
Your employer CANNOT apply for a work permit for you because he has to prove that you are permitted by law to work in this country. He is required to send your passport and visa to the Home Office when he applies for a work permit. But since your visa has already expired, your employer cannot send that to the Home Office, because he is breaking the law by employing you. If your employer is caught/found employing you, or any other person with no valid permit/visa to work in this country, your employer will be fined tens of thousands of pounds. That is how serious it is.
HOWEVER, there are options that you still have:
1. Leave this country. Go back to your country and re-apply for a visa to come back the proper way. (And next time you are allowed to come here, DO NOT overstay, whatever the reason. It only makes your case more complex and very difficult to deal with.)
2. Find a good REGISTERED lawyer/solicitor who can advise you on what to do in your situation. This will cost you a considerable amount of money of course, but it is well worth the effort.
3. Find advice from your nearest Citizens Advice Bureau. This is a free service that provides independent and confidential advice.
4. Find advice from your country’s Embassy. (Embassies are usually situated in London. You will have to find where your own country’s Embassy is situated).
I have provided links below that concern these options.
