How to apply for a UK work visa

A work visa is a document issued the government to allow foreigners to work in certain countries. Work visas are different from other types of visas, such as student visas or tour visas, which usually allow people to stay legally in their home country for short periods of time (usually less than six months). Instead, work visas allow people to enter into the country on a temporary basis. The visa allows them to work for up to 12 months (or more) before they have to leave and apply for a new visa.
UK Visa
Before starting a job in the UK, you will need to apply for a visa. A visa is not a guarantee of employment. It simply gives you permission to work. The UK has strict immigration laws, and the ability to work in the UK is restricted. If you are planning on applying for a work visa, it is important to know what you should do.
There are different categories of visas, and each has different requirements. The most important thing is that you must be able to prove that you can support yourself financially. This means that your salary must not be below a certain amount, or it will not get accepted as proof of financial support. A Skilled Worker visa allows you to enter or remain in the United Kingdom to work in an eligible job with an approved employer.
Eligibility
Your specific eligibility is determined your job. To be eligible for a Skilled Worker visa, you must meet the following requirements:
Work for a UK employer approved the Home Office.Have a ‘certificate of sponsorship’ from your employer detailing the position you’ve been offered in the UK.
Perform a job on the l of eligible occupations.
Be paid a minimum wage, the amount of which depends on the type of work you do.
You must be fluent in English and be able to speak, read, write, and understand it. When you apply, you will usually be required to demonstrate your command of the English language.

Extension
If you want to stay in the UK for an extended period of time, you may apply to extend your visa as many times as you wish, as long as you continue to meet the eligibility requirements.
After five years, you may be eligible to apply for permanent residence in the UK (also known as ‘indefinite leave to remain’). This gives you the right to live, work, and study in the country for as long as you want, as well as apply for benefits if you qualify.
