Yes, many U.S. work visas can be extended if your employer continues to require your services and you meet eligibility conditions. For instance, H-1B visas can be renewed up to six years, and L-1 visas up to five or seven years. While work visas are temporary, they can serve as a stepping stone toward permanent residency. Employers may sponsor eligible employees for an employment-based Green Card through categories such as EB-2 or EB-3. Once the immigrant petition is approved and your priority date is current, you can apply for adjustment of status or consular processing.
