Work Visa gives an applicant the ability to take a job in a country other than the one in which the applicant is a citizen.
There are different types of work visas. One kind may require the holder to have a local employer as a sponsor, and to return home if he/she loses the job. Another visa may be more general and may allow the holder to work in any job for a certain period of time.
Work visas are generally temporary, though most may be renewed.
A prior job offer from a sponsoring employer fast tracks the processing of a Work Permit.
A work permit is a general term for a legal authorization which allows an applicant to take employment overseas. Consultancies will accept the profiles which have a higher chance of success. And those who meet the evaluation criteria based on the selected country’s eligibility will be accepted.
