Approved I140, Possible next steps?

[darius]

I have a few questions with respect to an approved I140,

According to current USCIS policies:

- I need to wait 6 months after an approved I140 so that my application cannot be withdrawn/revoked by my company or USCIS (unless for any misconduct), so that my priority date is fixed, and so that I can also apply in future for cap-exempt H1b till my priority date is current?
- For any change in position or employer in the future, I still get to keep my priority date and cap-exempt H1b from my approved I140? I will however need to file a new PERM/I-140 petition for the new position or employer whenever my application gets reviewed by USCIS
- Do I still get to keep my priority date and cap-exempt H1b in future for a different company if for some reason my previous company with whom I have my I-140 approved shuts down in the future ?

Thanks in advance.

1. The employer can indeed revoke your I-140. That does not affect your Future H1 extensions if the I-140 has been pending more than 180 days.

2. You will need the sponsor to file  PERM etc., if you intend to change employers.

3. Usually.
