Form I-140

1. When that application itself is illegal or at least improper, I do not see how you can use any component of that with any degree of comfort.  
2. I would withdraw that I-485. I certainly think it is a bad idea. Even if it is approved, it has no value because it can be revoked at any point of time. 

1. I would say an average of a couple of years. 
2. Yes, it can be. Please go through my blogs and articles on the economic author page for more details on this issue.
3. It would work  just fine. Your lawyers can organize that.

When you actually file the PERM application (August 2022) you become eligible for a one year extension in August 2023 between January and August. You would not have a status to work unless you have some recapture time left. Needless to say if your PERM gets approved and your I-140 gets approved you can immediately.

Even if your lawyers do nothing to use the old priority date, that priority date is your right. The government itself is supposed to run a data sweep. Check their databases and give you the earliest date you are entitled to. If none of the documents reflect that you've been given the earlier priority date it is still not a problem. Hence there is no other procedure required for you to follow. You do not  have to be overly concerned about the attorneys using the old priority date.

It depends on a couple of things. First of all the regulations changed in your favor on January 17, 2017. Therefore, if the revocation occurred before January 17, 2017 chances are you might have lost even your priority date. On January 17, 2017 the laws changed and now the rule is if the moment your I-140 is approved the priority date is yours to keep. The second rule is if the I-140 stays approved for 180 days you also have the right to extend your H-1B and your spouse their H-4. There are two different rights  - right to keep your priority date the moment I-140 is approved and  the right to extend H-1B if the I-140 stays approved for 180 days. Hence this is a protection even if the employer revokes your H-1B.
