General Nonimmigrant Visa

Yes. Under federal regulations, if an employer terminates an H-1B employee before the end of their period of authorized stay, the employer is liable for the reasonable costs of return transportation to the worker's last place of foreign residence. This does not apply if the worker resigns voluntarily. If an employer refuses to provide this, the worker may file a complaint with the Department of Labor (DOL) Wage and Hour Division.

You remain in I-485 Pending status. Your status does not automatically convert to a Lawful Permanent Resident (LPR) just because the primary applicant was approved; each individual application must be adjudicated. As long as you have a valid Employment Authorization Document (EAD), you can continue to work legally in the United States. You are no longer in your previous non-immigrant status (like H-4) once you begin relying on the I-485 pending status or the EAD.
