The duration of a working visa depends on the country and type of visa. Typically, work visas can last anywhere from one to several years, with the option to renew or extend. For example:   – U.S. H-1B visa: Initially issued for 3 years, extendable for another 3 years (maximum 6 years). – UK Skilled Worker visa: Valid for up to 5 years before requiring renewal. – Canadian work visas: Generally valid for 1-2 years, with the possibility of extension.   Always check the specific rules for your visa type and destination country.
