I post here and put in touch with the company. Once contact is made they explain all. In the UK in this time is very easy to sponsor persons if the process is followed, must pass the English test. (of course not guarantee example person has crinal history)
The company will explain the process and time. They have engineers who once apply take 6-12 weeks to get approved. Right now successful applications are completed from India, Pakistan, Romania, the Philippines, Vietnam. These people already settled in the UK and working.
Uk is open to "skilled worker" we know relamination, motherboard level repair, software are classed as skilled worker.
All sponsors can be found on home office website, so anyone worried can check the status of the company with the UK home office.
