If you have a valid work visa, you are able to go to another country and find employment there for a designated amount of time. It’s possible that every country has a somewhat different process and set of conditions to meet in order to qualify for a work visa. These visas can either be temporary or permanent depending on the applicant’s needs. If the bearer of a temporary work visa wishes to extend his stay in the country for an additional period of time, he will need to apply for a renewal of his visa. The majority of the time, the employer will be the one to submit an application for a work permit visa. An application for a visa will be submitted by the employer to the relevant immigration authority of a particular nation.
