I am on H1B with my current employer and also have an approved H4 EAD (through my spouse’s employer). I am pursuing another career opportunity that doesn’t provide visa sponsorship -
If I am switching jobs and let go of my H1B status, do I need to file a COS with USCIS? Or does presenting the EAD to new employer at the time of joining is sufficient? Is COS approval a pre-req before taking a new job?
If I am in-between jobs, am I legally eligible to stay in US? Or COS filing with USCIS is mandatory? If yes to latter, how much of lead time should I consider to file COS before giving up H1B status with my current employer?
