There are 3 major steps involved in submitting an application for UK Skilled Worker Visa:
Step # 1: Sponsorship licence
The employer undertakes the first stage. They will apply directly for a sponsorship licence to the UKVI – UK Visas and Immigration and will be accordingly assessed.
Step # 2: Certificate of Sponsorship
The application for COS – Certificate of Sponsorship is filed by the approved sponsor for the occupation they would like to be filled by a non-resident worker. The immigrant can apply for the Work Visa once the COS is assigned.
Step # 3: Applying for the Skilled Worker Visa
The prospective employee will submit the Visa application in the final stage. This is with their unique COS number and evidence for fulfilling the requirements for Skilled Worker Visa.
