Whether you can change employers depends on the stage of your green card process. Early stages like PERM are employer-specific and cannot be transferred. Later stages may allow portability under certain conditions, but timing and job similarity matter greatly.

Sponsorship is voluntary, and employers may delay due to cost or uncertainty. Open communication helps, but you should not rely solely on verbal promises. Planning for visa expiration scenarios is critical.

Ultimately, your immigration future should not depend entirely on employer indecision. Exploring backup options and staying legally compliant gives you leverage and security.
