An H1B Transfer job refers to the process where an H1B visa holder changes employers while maintaining their lawful work status in the U.S. The new employer must file an H1B transfer petition with USCIS, but the employee can begin working for the new employer as soon as USCIS receives the petition. Unlike the initial H1B process, there is no cap or lottery for transfers, making it potentially faster. The employee does not need to wait for full approval to start working with the new employer. However, maintaining valid H1B status and complying with all regulations is essential.
