Hi i am an engineer working in a private company...

We would like to inform you that referring to the Kuwaiti Residence Law, if you have already lived or had a visa other than visa 18 for work in the private sector, the transfer shall be on the same visa with another sponsor under conditions requiring the following.
After the consent of the former sponsor and provided that the migrant worker has spent in the service of the employer for a period of not less than one year.
Original civil ID of the previous sponsor and a copy of it
Original civil ID of the current sponsor and a copy of it
Original civil ID of the sponsored and a copy thereof
Sponsor's passport
Two personal photos
Approving the signature and a copy thereof
The health insurance policy
and then go to the General Directorate of Immigration in the province you live in.
***In the event that the sponsor refuses to grant you a no-objection and the contract is fixed-term, the term of the contract must be completed and before the contract expires, a notice of his unwillingness to renew for the purposes of transferring the work visa, otherwise you have the right to go to the labor office and submit a complaint

Dear in all cases, the matter requires no objection from the sponsor to change work, but with the end of the work contract and unwillingness to renew and the employer's refusal to grant you permission to transfer, you can submit the complaint to the Affairs Office to grant you permission if it is proven that the illegal employer is abusing

Dear, one of the conditions for transferring residency and transferring sponsorship even with the end of the work contract is to obtain a no objection from the sponsor, but if it is proven that the employer is abusive in granting you permission, you can go to the Manpower Office and submit a complaint to obtain permission to change the employer with the help of the labor office at the time.
