Can I a job offer at UK with visa?

The job offer is not a sufficient reason to obtain a visa, and a work contract must be in place to be able to obtain an entry visa for the purpose of work.
If you want to get a job in the United Kingdom, this matter is achieved as follows:
The UK does not have a structured program to receive immigrants for work accordingly so you need to have a work contract with a company in the UK in order to get a residence permit for work.
We recommend that you obtain a tourist visa and then look for work during the validity of the visa, that you leave and return to your country and the employer will send the contract of employment to your place of residence so that you can re-enter the UK on the work visa. The employer is the one who takes all the procedures related to the issuance of the employment contract and work permit.
The documents to be submitted are:
- Certification of one of the foreign languages that are practiced within the company
- passport .
- Copy of academic certificates.
- A certificate not to issue criminal sentences against you
- Experience certificates for your business in the UAE
