Yes, you can obtain a green card through your job if your U.S. employer is willing to sponsor you for permanent residency. 

In some cases, you may be able to obtain a green card through employment without a specific job offer or employer sponsorship. For example, individuals with extraordinary ability in the sciences, arts, education, business, or athletics may qualify under the EB-1A category and self-petition for a green card. Another option is the National Interest Waiver (NIW), available under the EB-2 category, for those whose work substantially benefits the United States. These routes are ideal for researchers, entrepreneurs, or professionals with significant accomplishments who can demonstrate their value to the nation without going through the traditional labor certification process.

Many foreign workers in the U.S. start their journey on temporary work visas such as H-1B, L-1, or O-1, and later transition to permanent residency through employment-based green cards. If your employer is supportive, they can initiate the green card process while you’re working under a temporary visa. It's important to begin this process well before your visa expires due to processing times and annual green card quotas, especially for individuals from countries with high demand. This transition is a common and strategic pathway for skilled professionals who want to establish long-term residence in the U.S.
